Neurological disorders affect the brain and nervous system, causing a wide range of symptoms, from chronic pain and cognitive impairment to seizures and paralysis. In this article, we aim to provide information on the causes of neurological disorders, some types of neurological disorders, and available treatments.

What are Neurological Disorders
The nervous system is composed of nerves, the spinal cord, and the brain. Together, they regulate all bodily functions. There is a wide range of neurological disorders such as Amyotrophic Lateral Sclerosis (ALS), Atypical Parkinson’s, Bell’s Palsy, Cluster Headache, Compressive Myelopathy, Epilepsy, Migraine, Motor Neuron Disease, Multiple Sclerosis, Muscular Dystrophy, Neurogenic Bladder, Quadriplegia etc.
Neurological disorders are those that manifest as alterations in thought, emotion, or behaviour, resulting in either distress or a decrease in function. No matter the underlying cause, all neurological disorders are caused by damage to the nervous system. Where the damage occurs determines how much it affects the ability to communicate, see, hear, move, and think.

Types of Neurological Disorders
1. Paralysis: Loss of muscle function due to nerve damage or injury, resulting in impaired movement and sensation.
2. Stroke: Sudden interruption of blood flow to the brain, leading to cognitive and motor impairments.
3. Dementia: Progressive decline in cognitive function, memory, and decision-making, affecting daily life and independence.
4. Alzheimer’s Disease: A form of dementia marked by memory loss, confusion, and cognitive decline, often in older adults.
5. Parkinson’s Disease: Neurodegenerative disorder causing tremor and rigidity due to dopamine deficiency.
6. Epilepsy: A chronic neurological condition characterized by recurrent seizures or convulsions.
7. Migraine: Severe headaches with throbbing pain, often accompanied by nausea, light sensitivity, and visual disturbances.
8. Trigeminal Neuralgia: Intense facial pain due to trigeminal nerve dysfunction, causing stabbing or electric shock-like sensations.

Common Symptoms of Neurological Disorders
Headaches: Persistent headaches can be caused by various neurological conditions, including migraines, tension headaches, or intracranial pressure changes.
Seizures: Seizures result from abnormal electrical activity in the brain and are a hallmark symptom of epilepsy.
Numbness or tingling: These sensations may be due to nerve damage, as seen in conditions like peripheral neuropathy or multiple sclerosis.
Muscle weakness: Muscle weakness can be caused by diseases such as muscular dystrophy, myasthenia gravis, or motor neuron disorders.
Tremors: Uncontrolled shaking or tremors are common in Parkinson’s disease, essential tremors, and other movement disorders.
Cognitive changes: Conditions like Alzheimer’s disease or other dementias can lead to memory loss, confusion, and personality changes.
Vision problems: Disorders like optic neuritis can result in vision loss, while double vision is often seen in conditions affecting the cranial nerves.
Difficulty walking: Gait disturbances can be caused by various neurological conditions, including stroke, multiple sclerosis, or ataxia.
Speech problems: Speech difficulties can occur in conditions such as aphasia, dysarthria, or certain types of strokes affecting speech centres in the brain.

Causes of Neurological Disorders
Trauma: Head injuries can result in neurological disorders. Traumatic brain injury (TBI) can cause damage to brain tissue and lead to conditions like post-concussion syndrome.
Vascular Issues: Stroke occurs when there is a disruption in blood flow to the brain, often due to a blood clot or haemorrhage. This can result in various neurological deficits.
Infections: Infections can lead to neurological disorders. Bacterial infections like meningitis or encephalitis can lead to inflammation of the brain and associated disorders.
Toxic Exposure: Exposure to toxins like lead, mercury, or certain chemicals can damage the nervous system. Lead exposure, for example, can result in developmental delays and learning disabilities.
Degenerative Processes: Conditions like Alzheimer’s and Parkinson’s disease involve the degeneration of specific brain areas over time, leading to cognitive and motor impairments, respectively.
Genetic Factors: Some neurological disorders, like Huntington’s disease, are caused by mutations in specific genes. These mutations lead to the abnormal functioning of proteins, affecting nerve cells.

Understanding Neurological Disorders in Ayurveda
In Ayurveda, neurological disorders result from imbalances in the doshas—Vata, Pitta, and Kapha—fundamental energies governing the body. The majority of these disorders are attributed to Vata dosha imbalance, referred to as Vatavyaadhi, signifying health issues caused by Vata Dosha disruption. Let’s delve into this perspective:
Vata Dosha: When Vata Dosha is aggravated it can lead to conditions like anxiety, tremors, and insomnia.
Pitta Dosha: When Pitta Dosha is imbalanced it may contribute to inflammatory brain conditions.
Kapha Dosha: When Kapha Dosha is imbalanced it can lead to cognitive stagnation and depression.

Treatment and Management
Treatment options for neurological disorders depend on the underlying cause and specific symptoms. They may include:

Medications:

• Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) are used to treat severe muscle cramps.
• Clot-busting drugs are administered within a specific time window after an ischemic stroke to dissolve blood clots and restore blood flow.
• Anticoagulants or antiplatelet drugs are prescribed to prevent the formation of blood clots and reduce the risk of stroke recurrence.
• Medications may be given to manage pain, prevent seizures, control high blood pressure, or manage other conditions associated with stroke or paralysis.

Rehabilitation therapy:

• Physical therapy is used to improve strength, balance, coordination, and mobility through exercises and specialized techniques.
• Occupational therapy is used to enhance the ability to perform activities of daily living, such as self-care, using adaptive devices, and modifying the environment.
• Speech therapy helps individuals regain communication skills, improve speech and language abilities, and address swallowing difficulties.
• Rehabilitation nursing is used to provide specialized care to manage complications, promote recovery, and support functional independence.

Assistive devices and mobility aids:

• Individuals with mobility impairments may benefit from the use of a mobility aid, such as a wheelchair, walker, cane, or braces, to enable them to move around independently.
• Adaptive equipment can be used to facilitate activities of everyday life, such as dressing, meals, and personal grooming.
• Augmentative and Alternative Communication Devices (AACs) can help people with speech impairments to communicate their thoughts and feelings.

Surgery:

• Carotid endarterectomy is a surgical procedure that removes plaque from the arteries of the carotid to reduce the risk of stroke.
• Surgical procedures may be employed to address the root causes of paralysis, including spinal cord compression and nerve damage.

Supportive care:

• Individuals affected by paralysis or stroke may benefit from psychological support services such as counselling, support groups and therapy, which can assist in managing the emotional distress associated with the condition.
• Modifying the living space to improve accessibility and safety, including the installation of grab bars, ramps or stairlifts.

Palliative care by SGP’s PSA:

• Provides relief from symptoms with medications.
• Helps individuals cope with the emotional consequences of living with a blood disorder through counselling and support groups.

Conclusion
Neurological disorders are typically treated on a case-by-case basis and may be managed by a multi-disciplinary team of medical professionals, such as neurologists, physiotherapists, rehabilitation specialists, nurse practitioners, and therapists.
It is essential to seek prompt medical attention for stroke-related symptoms, as timely treatment can significantly improve outcomes. Rehabilitation and supportive care play a crucial role in maximizing functional independence, promoting recovery, and improving the quality of life in individuals with neurological disorders.
