CENTRAL NERVOUS SYSTEM DISORDERS & PHARMACOTHERAPY
Central Nervous System (CNS) disorders affect the brain and spinal cord and can cause a wide range of symptoms — from seizures and tremors to memory loss and headaches. These conditions significantly impact daily life and require proper understanding and management.
This guide explains five major CNS disorders — Epilepsy, Parkinson’s Disease, Alzheimer’s Disease, Stroke, and Migraine — including their causes, symptoms, and management.
Epilepsy:
What is Epilepsy?
Epilepsy is a neurological disorder characterized by recurrent seizures due to abnormal electrical activity in the brain.
Types of Seizures:
- Partial (focal) seizures
- Generalized seizures
- Absence seizures
- Myoclonic seizures
- Status epilepticus
Symptoms:
- Seizures or convulsions
- Loss of consciousness
- Confusion
- Jerking movements
Management:
- Antiepileptic drugs (Carbamazepine, Phenytoin, Valproate)
- Ketogenic diet (in selected cases)
- Vagus nerve stimulation
Parkinson’s Disease:
What is Parkinson’s Disease?
Parkinson’s disease is a neurodegenerative disorder caused by loss of dopamine neurons affecting movement.
- Tremor
- Rigidity
- Bradykinesia
- Postural instability
Management:
- Levodopa + Carbidopa
- Dopamine agonists
- MAO-B inhibitors
Alzheimer’s Disease:
A progressive disorder causing memory loss and cognitive decline.
- Memory loss
- Confusion
- Personality changes
- Donepezil
- Memantine
Stroke:
Stroke occurs due to interruption of blood supply to the brain.
- Ischemic
- Hemorrhagic
- tPA (emergency)
- Antiplatelets
- Rehabilitation
Migraine:
Migraine is a neurological condition causing severe headaches with nausea and sensitivity to light.
- Throbbing headache
- Nausea
- Sensitivity to light
- NSAIDs
- Triptans
- Preventive therapy
Summary:
CNS disorders require early diagnosis and proper pharmacological and non-pharmacological management to improve patient outcomes.
