A stroke occurs when blood flow to part of the brain is interrupted or reduced, leading to brain cell damage. One of the common consequences is facial weakness or paralysis, also called post-stroke facial palsy, which may involve drooping of the mouth, inability to smile symmetrically, difficulty closing the eye, or impaired facial expression. Understanding the causes and risk factors can help in prevention, early recognition, and timely rehabilitation.

---

1. Causes of Post-Stroke Facial Weakness

A. Ischemic Stroke

1. Occurs due to blockage of a blood vessel supplying the brain.

2. If the stroke affects areas controlling facial muscles (such as the motor cortex or corticobulbar tract), it can result in facial droop or weakness on one side of the face.

B. Hemorrhagic Stroke

1. Bleeding within the brain can damage nerves that control facial movements.

2. Increased intracranial pressure may also compress neural pathways, causing asymmetry in facial function.

C. Brainstem Stroke

1. The brainstem houses the facial nerve nuclei.

2. A stroke in this region may directly cause facial paralysis, often affecting both upper and lower parts of the face, unlike cortical strokes that may spare the forehead.

D. Secondary Complications

1. Swelling or edema in brain tissue after stroke

2. Nerve inflammation or neuropathy affecting facial muscles

3. Muscle disuse if rehabilitation is delayed

---

2. Risk Factors for Post-Stroke Facial Weakness

Several conditions increase the risk of stroke and therefore post-stroke facial complications:

A. Cardiovascular Risk Factors

1. Hypertension (high blood pressure)

2. Atherosclerosis (hardening of arteries)

3. Heart disease (e.g., atrial fibrillation)

B. Metabolic Disorders

1. Diabetes mellitus

2. High cholesterol levels

C. Lifestyle Factors

1. Smoking

2. Excessive alcohol consumption

3. Physical inactivity

D. Age and Genetics

1. Risk increases after 55 years of age

2. Family history of stroke or cardiovascular disease

E. Previous Stroke or Transient Ischemic Attack (TIA)

1. Patients with prior strokes are more prone to recurrent stroke and facial weakness.

F. Neurological Conditions

1. Pre-existing neurological disorders may worsen facial recovery after stroke.

---

3. Importance of Early Recognition

Early recognition of facial droop or asymmetry is critical. Symptoms may include:

1. Difficulty smiling or frowning

2. Drooping eyelid or corner of the mouth

3. Drooling or impaired speech articulation

4. Inability to close one eye fully

Prompt medical evaluation ensures timely treatment, reducing long-term disability.

---

4. Remedies and Management

While prevention of stroke is the primary strategy, post-stroke facial weakness can be managed with:

1. Physical therapy: Targeted facial exercises to improve symmetry

2. Electrical stimulation: Improves muscle activation

3. Speech therapy: If facial weakness affects articulation or swallowing

4. Botulinum toxin: In some cases to manage spasticity

5. Surgery: Rarely, for long-term severe facial paralysis

Facial weakness after a stroke, often called post-stroke facial palsy, occurs when the neural pathways controlling facial muscles are damaged. Recognizing these symptoms early is critical because prompt rehabilitation can significantly improve recovery. The severity and presentation depend on the type, location, and extent of the stroke.

---

1. Facial Drooping

The most obvious sign is drooping of one side of the face, often affecting:

1. Corner of the mouth (difficulty smiling symmetrically)

2. Eyelid or eyebrow (partial eyelid closure, uneven brow height)

Patients may notice that one side of their face appears “asymmetrical,” especially when trying to express emotion.

---

2. Difficulty in Voluntary Facial Movements

1. Trouble raising eyebrows or wrinkling the forehead

2. Inability to close the eye fully on the affected side

3. Difficulty puckering lips, smiling, or frowning

4. Reduced ability to blow out cheeks

This is caused by paralysis or weakness of the facial muscles controlled by the facial nerve (cranial nerve VII).

---

3. Impaired Speech (Dysarthria)

Facial weakness may interfere with:

1. Clear pronunciation of words

2. Controlling airflow for speech

3. Movements needed for consonant sounds

Patients may notice slurred speech or changes in voice clarity.

---

4. Drooling or Difficulty Controlling Saliva

Weak lip muscles can make it difficult to keep saliva inside the mouth, causing:

1. Drooling, especially when speaking or eating

2. Difficulty eating or drinking without spilling

This may contribute to social discomfort and challenges in daily activities.

---

5. Eye-Related Symptoms

1. Inability to blink fully

2. Dry eyes due to incomplete closure (exposing cornea)

3. Increased risk of eye irritation or infection

These occur because the orbicularis oculi muscle is often affected in facial nerve involvement.

---

6. Reduced Facial Expression

Patients may notice a “flat” facial appearance on one side:

1. Difficulty showing emotions (smile, frown)

2. Reduced movement of cheeks or jaw

3. Impaired ability to convey nonverbal cues

This can affect social interactions and emotional expression.

---

7. Sensory Changes

Although post-stroke facial weakness primarily affects motor function, some patients may experience:

1. Tingling or numbness

2. Altered sensation around the mouth, cheek, or forehead

These symptoms may indicate additional nerve involvement.

---

8. Sudden Onset

A key feature of post-stroke facial weakness is its sudden onset, often accompanied by other stroke signs:

1. Weakness in the arm or leg

2. Difficulty speaking or understanding language

3. Visual disturbances

4. Severe headache or dizziness

Recognizing facial droop in combination with these warning signs can be life-saving, prompting immediate medical attention.

Post-stroke facial weakness, or facial palsy following a cerebrovascular event, is primarily caused by damage to the facial nerve pathways in the brain. Accurate diagnosis is crucial to determine the extent of nerve involvement, rule out other conditions, and plan effective rehabilitation. Diagnosis involves a combination of clinical assessment, imaging studies, and specialized tests.

---

1. Detailed Medical History

The first step in diagnosing post-stroke facial weakness involves gathering a comprehensive medical history:

1. Timing and onset of facial weakness (sudden onset often indicates stroke)

2. Presence of other stroke symptoms such as arm or leg weakness, speech difficulties, or visual changes

3. Previous history of stroke, transient ischemic attack (TIA), or cardiovascular disease

4. Medication history, including anticoagulants, antihypertensives, and diabetes medications

5. Risk factor assessment: hypertension, diabetes, smoking, high cholesterol

A thorough history helps differentiate stroke-related facial weakness from other causes, such as Bell's palsy, infections, or tumors.

---

2. Physical and Neurological Examination

A detailed examination is key to evaluating the severity and type of facial weakness.

A. Cranial Nerve Assessment

The clinician evaluates the facial nerve (cranial nerve VII) for:

1. Symmetry at rest and during movement

2. Ability to raise eyebrows, close eyes, smile, frown, and puff cheeks

3. Muscle tone and strength

B. Neurological Evaluation

Other neurological functions are assessed to identify associated stroke deficits:

1. Limb strength and coordination

2. Reflexes

3. Speech and language abilities

4. Sensory function

Facial weakness that spares the forehead often indicates upper motor neuron involvement (cortical stroke), while weakness of the entire side suggests lower motor neuron involvement.

---

3. Imaging Studies

Imaging helps confirm the diagnosis of stroke and locate the lesion causing facial weakness.

A. Magnetic Resonance Imaging (MRI)

1. Detects ischemic or hemorrhagic stroke in the brain

2. Evaluates brainstem involvement, which may directly affect the facial nerve nuclei

3. Provides high-resolution images of soft tissue structures

B. Computed Tomography (CT) Scan

1. Often used in acute stroke settings

2. Quickly identifies bleeding, infarction, or mass lesions

3. Helps rule out other causes of sudden facial weakness

---

4. Electrophysiological Testing

Electromyography (EMG)

1. Measures the electrical activity of facial muscles

2. Assesses the degree of nerve damage

3. Helps guide prognosis and rehabilitation strategies

Nerve Conduction Studies (NCS)

1. Evaluate signal transmission along the facial nerve

2. Differentiate stroke-related facial weakness from peripheral nerve disorders

---

5. Laboratory and Ancillary Tests

While not directly diagnostic for facial weakness, labs can identify underlying stroke risk factors:

1. Blood sugar levels (diabetes)

2. Lipid profile (cholesterol)

3. Coagulation profile (risk of clot formation)

4. Inflammatory markers in specific cases

---

6. Differential Diagnosis

Accurate diagnosis requires ruling out other causes of facial paralysis, including:

1. Bell's palsy (idiopathic facial nerve palsy)

2. Tumors compressing the facial nerve

3. Infection (Lyme disease, herpes zoster)

4. Trauma or surgery-related nerve injury

Clinical evaluation combined with imaging helps differentiate stroke-related facial weakness from these conditions.

Post-stroke facial weakness (or facial palsy) results from damage to the neural pathways controlling facial muscles. While some recovery can occur naturally in the first few weeks, timely and targeted treatment significantly improves functional outcomes, facial symmetry, and quality of life. Treatment is typically multidisciplinary, combining physical therapy, medication, supportive care, and, in select cases, surgical interventions.

---

1. Physical Therapy and Facial Exercises

Facial rehabilitation is the cornerstone of post-stroke recovery.

A. Active Facial Exercises

These exercises target affected muscles to restore movement and improve symmetry:

1. Raising eyebrows and frowning

2. Closing eyes tightly and blinking

3. Smiling and puckering lips

4. Puffing cheeks and moving air from side to side

Regular, guided exercises help maintain muscle tone, prevent contractures, and promote neural plasticity.

B. Mirror Therapy

Patients perform exercises in front of a mirror to improve visual feedback, enhance motor control, and encourage symmetrical movements.

C. Neuromuscular Re-education

Therapists may use techniques like tapping, massage, or resistance training to improve coordination and strengthen facial muscles.

---

2. Electrical Stimulation Therapy

Transcutaneous electrical nerve stimulation (TENS) or low-intensity electrical stimulation can:

1. Activate paralyzed facial muscles

2. Promote neural regeneration

3. Improve muscle tone and voluntary movement

Therapy is typically supervised by a trained physiotherapist to avoid over-stimulation or muscle fatigue.

---

3. Speech and Swallowing Therapy

Post-stroke facial weakness often impacts:

1. Speech (dysarthria): Difficulty articulating words due to weakened lip, tongue, or cheek muscles

2. Swallowing (dysphagia): Increased risk of aspiration

A speech-language pathologist (SLP) provides:

1. Lip and tongue exercises

2. Breathing control techniques

3. Swallowing rehabilitation strategies

4. Communication strategies to improve speech clarity

---

4. Medications and Adjunct Treatments

While no medication directly reverses facial paralysis caused by stroke, some treatments may support recovery:

1. Botulinum toxin (Botox): Used in cases of spasticity or involuntary muscle contractions to restore balance and improve facial symmetry

2. Neurotrophic or nerve-supporting supplements: Vitamins B1, B6, and B12 may support nerve health

3. Pain management: Analgesics for discomfort caused by muscle stiffness or nerve irritation

---

5. Surgical Options

Surgery is reserved for long-term, severe facial paralysis that does not improve with rehabilitation:

1. Nerve grafting or facial reanimation procedures: Reconnect or redirect healthy nerves to restore movement

2. Muscle transfer surgeries: Use of donor muscles to replace paralyzed muscles

3. Eyelid or lip procedures: Correct asymmetry, improve eye closure, and prevent complications like corneal damage

Surgical intervention is generally considered after 12-18 months of failed functional recovery.

---

6. Supportive and Lifestyle Measures

Recovery can be enhanced by daily care and lifestyle adjustments:

1. Eye protection: Moisturizing drops, protective glasses, or taping the eye closed during sleep

2. Massage and soft tissue mobilization: Prevents stiffness and improves circulation

3. Stress management: Yoga, meditation, and relaxation techniques support neural recovery

4. Nutritional support: Adequate protein, vitamins, and hydration promote muscle and nerve healing

---

7. Multidisciplinary Approach

Optimal outcomes require a team-based approach:

1. Neurologists: Evaluate stroke severity and coordinate care

2. Physiotherapists: Guide facial exercises and neuromuscular re-education

3. Speech-language pathologists: Address speech and swallowing issues

4. Occupational therapists: Help adapt daily activities

5. Ophthalmologists or plastic surgeons: Manage eye and facial symmetry issues

Post-stroke facial weakness, often presenting as facial droop, paralysis, or asymmetry, can significantly affect a patient's quality of life, communication, and self-esteem. While some strokes and subsequent facial weakness cannot be fully prevented, a combination of primary prevention strategies, early rehabilitation, and long-term management can reduce severity, promote recovery, and minimize complications.

---

1. Prevention of Post-Stroke Facial Weakness

Preventing post-stroke facial weakness primarily involves reducing the risk of stroke itself:

A. Control of Cardiovascular Risk Factors

1. Hypertension management: Maintain blood pressure within a healthy range

2. Diabetes control: Regular monitoring of blood sugar and medication adherence

3. Cholesterol regulation: Healthy diet, statins if indicated

B. Healthy Lifestyle

1. Regular physical activity: Improves circulation and cardiovascular health

2. Balanced diet: Rich in fruits, vegetables, whole grains, and lean proteins

3. Avoid smoking and excessive alcohol: Both increase stroke risk

C. Early Detection of Transient Ischemic Attacks (TIAs)

1. TIAs, or “mini-strokes,” often precede full strokes

2. Immediate medical attention and preventive measures (anticoagulants, lifestyle changes) can reduce stroke-related facial weakness

D. Managing Underlying Heart Conditions

1. Treat atrial fibrillation or other arrhythmias

2. Monitor heart health to prevent embolic strokes

---

2. Early Management After Stroke

Early intervention is critical for improving facial recovery and preventing long-term disability.

A. Prompt Medical Care

1. Immediate evaluation of stroke symptoms ensures timely reperfusion therapy (e.g., thrombolytics) to limit brain damage

2. Early neurological assessment identifies the extent of facial nerve involvement

B. Initiation of Rehabilitation

1. Physical therapy: Gentle facial exercises as soon as medically safe

2. Speech and swallowing therapy: If oral or speech muscles are affected

3. Mirror therapy and neuromuscular re-education: Begin early to encourage symmetry and neural plasticity

---

3. Long-Term Management Strategies

Even after the acute stroke phase, ongoing management is essential.

A. Facial Exercises and Therapy

1. Daily exercises help restore muscle strength and coordination

2. Techniques may include:

   1. Smiling, frowning, raising eyebrows

   2. Puckering lips, blowing cheeks

   3. Blinking and eye closure exercises

B. Eye Care

   1. Lubricating eye drops

   2. Protective eyewear during daytime

   3. Eye taping at night to prevent corneal damage

C. Pain and Muscle Stiffness Management

1. Massage, warm compresses, and gentle stretching reduce discomfort and spasticity

2. Botox or other targeted interventions may be used for abnormal muscle contractions

D. Speech and Swallowing Support

1. Ongoing work with a speech-language pathologist ensures safe swallowing, clear speech, and improved communication

2. Adaptive strategies may include pacing, articulation exercises, and assistive devices if needed

E. Psychological and Social Support

1. Facial weakness can impact self-esteem, social interaction, and mental health

2. Counseling, support groups, or cognitive-behavioral therapy can help patients cope with changes in appearance and function

---

4. Lifestyle and Secondary Prevention

To reduce recurrence and protect long-term facial function:

1. Maintain a heart-healthy diet and weight

2. Engage in regular low-impact exercise

3. Continue prescribed medications for stroke prevention (antiplatelets, anticoagulants, antihypertensives)

4. Avoid smoking and limit alcohol

5. Attend regular follow-up with neurologists and therapists

Post-stroke facial weakness, or facial palsy following a cerebrovascular event, can significantly affect both physical function and quality of life. While many patients experience partial recovery over time, there are potential short-term and long-term complications that can arise if the condition is severe, left untreated, or poorly managed. Understanding these complications helps patients, caregivers, and clinicians anticipate challenges and intervene appropriately.

---

1. Functional Complications

A. Difficulty with Speech (Dysarthria)

Facial weakness may impair lip, cheek, and jaw movement, affecting articulation. Patients often experience:

1. Slurred or unclear speech

2. Difficulty forming consonants (e.g., “p,” “b,” “m”)

3. Reduced vocal clarity in social or professional settings

This can limit effective communication and social interaction.

B. Swallowing Difficulties (Dysphagia)

Weakness of facial muscles can compromise swallowing:

1. Drooling and difficulty controlling saliva

2. Increased risk of choking or aspiration

3. Reduced ability to eat certain textures or solids safely

Swallowing difficulties can lead to malnutrition, dehydration, and respiratory infections.

C. Eye Complications

Incomplete eyelid closure or weak blinking may cause:

1. Dry eyes and irritation

2. Corneal ulcers or infections

3. Excessive tearing due to improper drainage

Proper eye care, including artificial tears or protective taping, is critical.

---

2. Muscular and Structural Complications

A. Muscle Contractures and Spasticity

Without rehabilitation, facial muscles may stiffen, leading to:

1. Permanent asymmetry

2. Difficulty in voluntary facial movements

3. Pain or discomfort during expressions

B. Synkinesis

Improper nerve regeneration can cause abnormal involuntary movements of facial muscles:

1. Eye closure during smiling

2. Mouth movement during blinking

3. Muscle twitching or tightness

Synkinesis can interfere with coordinated facial expression and appearance.

---

3. Psychological and Social Complications

Facial weakness can profoundly impact mental health and social functioning:

1. Low self-esteem or embarrassment due to asymmetry

2. Social withdrawal to avoid attention to facial droop

3. Depression or anxiety related to appearance or functional limitations

Early psychosocial support and counseling improve coping and emotional well-being.

---

4. Long-Term Functional Limitations

Even with rehabilitation, some patients may experience:

1. Residual asymmetry in facial expression

2. Persistent drooling or difficulty controlling saliva

3. Reduced ability to convey emotions non-verbally

4. Difficulty with oral hygiene or dental care due to reduced lip closure

These limitations may persist for months or even years, depending on stroke severity and therapy adherence.

---

5. Risk of Secondary Medical Complications

1. Aspiration pneumonia: Resulting from impaired swallowing

2. Malnutrition or dehydration: From difficulty eating and drinking

3. Eye infections: From corneal exposure and dryness

4. Muscle atrophy: If facial muscles are not exercised consistently

Timely intervention with rehabilitation, eye care, and supportive therapies can minimize these risks.

Post-stroke facial weakness, also referred to as post-stroke facial palsy, can have significant impacts on daily function, communication, emotional well-being, and social interactions. Even after initial recovery, patients may face residual weakness, asymmetry, or difficulty performing normal facial movements. Living with this condition requires a combination of rehabilitation, lifestyle adjustments, medical support, and psychosocial coping strategies to maximize quality of life.

---

1. Adapting to Facial Weakness

Patients often experience noticeable facial asymmetry, drooping of one side of the mouth, or difficulty closing an eye. While these physical changes can be distressing, adapting involves:

1. Learning compensatory movements (e.g., using stronger muscles on the unaffected side)

2. Practicing daily facial exercises to maintain muscle tone and improve symmetry

3. Using mirror feedback during exercises to improve control and coordination

These strategies can help patients regain confidence in facial expressions and reduce functional limitations.

---

2. Managing Daily Activities

Post-stroke facial weakness can affect routine activities such as:

1. Eating and drinking: Difficulty controlling saliva may require small bites, slower eating, or adaptive utensils

2. Oral hygiene: Weak lip closure may necessitate careful brushing and flossing

3. Eye care: Patients with incomplete eye closure should use lubricating drops, eye patches, or protective glasses to prevent dryness and injury

Occupational therapists can provide guidance on modifying activities for safety and independence.

---

3. Communication and Social Interaction

Facial weakness may impair speech clarity, emotional expression, and nonverbal communication. Patients can:

1. Work with a speech-language pathologist for articulation exercises and swallowing strategies

2. Use gestures or assistive communication tools if speech is severely affected

3. Practice slow and deliberate speech to enhance clarity in conversations

Support from family, friends, and caregivers is essential to encourage participation in social activities despite facial changes.

---

4. Emotional and Psychological Well-Being

Living with facial weakness can cause emotional challenges:

1. Anxiety or embarrassment over appearance

2. Depression or frustration due to functional limitations

3. Reduced self-esteem from social or professional difficulties

Counseling, cognitive-behavioral therapy, and participation in support groups for stroke survivors can help patients cope with these emotional impacts. Encouraging social interaction and celebrating small progress in rehabilitation boosts confidence and motivation.

---

5. Rehabilitation and Long-Term Therapy

Ongoing therapy is critical for maintaining gains and preventing complications:

1. Facial physiotherapy: Exercises to strengthen muscles and improve coordination

2. Electrical stimulation therapy: May aid in muscle activation

3. Speech and swallowing therapy: Addresses dysarthria and dysphagia

4. Regular follow-ups: Monitoring recovery progress and adjusting therapy as needed

Consistency in these interventions greatly improves functional outcomes and facial symmetry.

1. What is Post-Stroke Facial Paralysis and why does it happen?

Post-stroke facial paralysis occurs when a stroke damages the areas of the brain responsible for controlling facial muscles. This leads to weakness, asymmetry, drooping of the mouth or eyelid, difficulty smiling, and reduced facial expressions. The stroke disrupts the brain's nerve pathways, making it difficult for signals to reach facial muscles. Treatment focuses on restoring muscle strength, improving nerve function, and enhancing facial symmetry through rehabilitation therapies.

---

2. What are Post-Stroke Facial Remedies and treatment options?

Treatment for post-stroke facial paralysis is usually multidisciplinary and may include:

1. Facial physiotherapy (muscle strengthening, stretching, neuromuscular retraining)

2. Speech therapy (to improve oral movements and speech clarity)

3. Electrical stimulation (to activate weakened facial muscles)

4. Botox injections (to treat muscle tightness or spasms)

5. Plastic or reconstructive surgery in severe cases

6. Medications to reduce spasms or inflammation
   Treatment recommendations depend on severity, duration since stroke, and patient goals.

---

3. How long does it take to recover from post-stroke facial paralysis?

Recovery varies greatly. Some individuals begin to regain facial movement within weeks, while others may require months or even years of therapy. Key factors include:

1. Severity of the stroke

2. How early rehabilitation begins

3. Patient age and health

4. Consistency with exercises
   Most noticeable improvements occur within 3-6 months, but continued therapy can lead to gains even after a year.

---

4. Can facial paralysis after a stroke be completely cured?

Complete recovery is possible for many patients, especially when treatment starts early and symptoms are mild. However, some may experience lingering weakness, asymmetry, or muscle stiffness (synkinesis). Even in cases where full recovery is not possible, significant improvement in function and appearance can be achieved with proper therapy, electrical stimulation, and surgical options.

---

5. What is facial retraining therapy, and how does it help?

Facial retraining therapy is a specialized rehabilitation technique that focuses on:

1. Re-teaching the brain how to send signals to facial muscles

2. Improving symmetry during facial expressions

3. Reducing abnormal movements and spasms

4. Enhancing muscle control through guided exercises
   Therapists use methods like mirror exercises, targeted facial movements, breathing control, and sensory feedback. This therapy significantly improves emotional expression and quality of life.

---

6. Are electrical stimulation and biofeedback effective for post-stroke facial recovery?

Yes. Electrical stimulation and biofeedback can be beneficial when used correctly under professional supervision:

1. Electrical stimulation helps activate muscles that are weak or unable to move voluntarily.

2. Biofeedback teaches patients to control facial muscles using real-time visual or auditory feedback.
   These methods accelerate muscle re-education and improve coordination, especially in moderate to severe paralysis.

---

7. When is surgery recommended for post-stroke facial paralysis?

Surgery is considered for patients who do not respond sufficiently to rehabilitation. Surgical options include:

1. Nerve grafts or nerve transfers to restore muscle function

2. Facial reanimation procedures to improve smile symmetry

3. Eyelid surgery to help with blinking and eye protection

4. Muscle transfer procedures for improved facial movement
   These procedures can significantly enhance appearance, symmetry, and facial control.

---

8. What exercises can help with post-stroke facial recovery?

Common therapeutic exercises include:

1. Eyebrow raising and forehead stretching

2. Gentle eye-closing and blinking practice

3. Nose wrinkling and cheek lifting

4. Smiling exercises (with and without mirror support)

5. Puckering lips, whistling, and blowing air

6. Controlled jaw movements
   Repetition and consistency are key. Exercises should always be guided by a trained therapist to avoid improper movements or synkinesis.

---

9. How can Botox help in post-stroke facial paralysis?

Botox (Botulinum toxin) injections are used to:

1. Reduce muscle tightness or spasms

2. Improve facial symmetry

3. Manage synkinesis (involuntary movements)

4. Enhance comfort and appearance
   Botox relaxes overactive muscles, allowing weaker muscles to function better. It is particularly helpful in long-standing paralysis cases or when the facial muscles become stiff.

---

10. What lifestyle changes support Post-Stroke Facial Remedy?

Certain lifestyle modifications enhance recovery and overall well-being:

1. Healthy diet rich in antioxidants and omega-3 fatty acids

2. Regular exercise to improve blood flow and brain health

3. Stress management through meditation or breathing exercises

4. Adequate hydration and rest

5. Avoiding smoking and excessive alcohol, which slow healing
   Emotional support, counseling, and family involvement also play a key role in long-term recovery.
