- Antiepileptic Drugs (AEDs): Newer AEDs with fewer side effects and better efficacy for seizure control.
- Migraine Treatments: CGRP inhibitors and other novel therapies for preventing and treating migraines.
Neuromodulation Techniques
Neuromodulation involves altering nerve activity through electrical or pharmaceutical agents to treat neurological conditions.
Key Neuromodulation Techniques:
- Deep Brain Stimulation (DBS): Implantation of electrodes in the brain to treat movement disorders like Parkinson’s disease and dystonia.
- Transcranial Magnetic Stimulation (TMS): Non-invasive technique using magnetic fields to stimulate nerve cells in the brain, used for depression and migraine.
- Vagus Nerve Stimulation (VNS): Implanted device stimulating the vagus nerve, used for epilepsy and depression.
Stem Cell Therapy
Stem cell therapy is an emerging treatment with the potential to regenerate damaged tissues and treat various neurological disorders.
Applications of Stem Cell Therapy:

- Stroke Recovery: Enhancing brain repair and improving outcomes in stroke patients.
Gene Therapy
Gene therapy aims to treat neurological disorders by delivering corrected genes to affected cells.
Applications of Gene Therapy:
- Inherited Neurological Disorders: Treatment for conditions like spinal muscular atrophy (SMA) through gene replacement therapy.
- Neurodegenerative Diseases: Potential therapies for diseases like Alzheimer’s and Parkinson’s through gene editing technologies.
Comprehensive Care Strategies
Multidisciplinary Approach
A multidisciplinary approach involves collaboration among various healthcare professionals to provide holistic care for neurological patients.
Components of Multidisciplinary Care:
- Neurologists: Specialists in diagnosing and treating neurological disorders.
