Study Notes
- Neurological disorders affect the brain, spinal cord, and nerves.
Seizure Disorders
- Characterized by hyperexcitable and hypersynchronous neuronal activity, often due to ion channel dysfunction.
- Involves an imbalance between excitatory neurotransmitters like glutamate and inhibitory neurotransmitters like GABA.
- Generalized seizures manifest as loss of consciousness, tonic-clonic, absence, myoclonic, or atonic activity.
- Partial seizures can be simple or complex and are localized to specific brain regions.
- Medications work by increasing GABA, blocking Na+ and Ca2+ channels, and reducing glutamate activity to stabilize neuronal excitability.
Alzheimer's Disease
- A progressive neurodegenerative condition is caused by amyloid-beta plaques and tau protein tangles in the brain.
- There is a decrease in acetylcholine (ACh) and glutamate dysfunction.
- Classic symptoms: memory loss, disorientation, confusion, behavioral changes, and severe cognitive decline.
- Treatment strategies focus on increasing acetylcholine levels and regulating glutamate activity to prevent excitotoxicity and neuronal death.
Huntington's Disease
- An autosomal dominant genetic disorder that leads to atrophy of the caudate nucleus and putamen.
- There are decreased levels of GABA and ACh with elevated dopamine.
- It manifests as chorea, cognitive decline, psychiatric symptoms, and progressive rigidity.
- Management involves reducing excess dopamine to alleviate involuntary movements (chorea) and controlling psychiatric symptoms
- Antipsychotics like Haloperidol and SSRIs such as Fluoxetine and Sertraline can control Psychiatric symptoms.
Parkinson's Disease
- Characterized by the loss of dopaminergic neurons in the substantia nigra, with Lewy bodies accumulation.
- Associated with decreased dopamine and increased acetylcholine levels.
- Prominent features include resting tremor, bradykinesia, rigidity, postural instability, and a shuffling gait.
- Medications aim to increase dopamine levels, stimulate dopamine receptors, reduce dopamine breakdown by inhibiting MAO-B or COMT enzymes, and restore the dopamine-ACh balance to reduce tremors.
Multiple Sclerosis (MS)
- An autoimmune condition involving demyelination of CNS neurons and the formation of plaques.
- Inflammation disrupts synaptic function, without direct neurotransmitter involvement.
- Common symptoms are vision problems, muscle weakness, spasticity, fatigue, and cognitive impairment.
- Treatment focuses on suppressing the immune system and reducing inflammation to manage acute flare-ups
- Managing muscle spasticity and fatigue are key for symptom management.
Amyotrophic Lateral Sclerosis (ALS)
- Involves the degeneration of upper and lower motor neurons and is linked to glutamate excitotoxicity.
- Muscle weakness, fasciculations, and progressive paralysis manifest while cognition is mostly spared.
- Management strategies include reducing glutamate toxicity using glutamate inhibitors and reducing oxidative stress with antioxidants.
- Symptomatic support for muscle spasticity is important.
- Respiratory support should be provided as the disease progresses.
Stroke (CVA)
- Ischemic stroke involves blocked blood flow, while hemorrhagic stroke involves a ruptured vessel.
- Glutamate accumulation leads to oxygen deprivation, ATP depletion, inflammation, and cell death in neurons.
- Neurons suffer oxygen deprivation, ATP depletion, inflammation, and cell death.
- Treatment for ischemic stroke focuses on breaking down clots with tPA (Tissue Plasminogen Activator) given within 3-4.5 hours, while long-term prevention includes antiplatelets (Aspirin, Clopidogrel) and anticoagulants like Warfarin for atrial fibrillation; managing blood pressure is critical in hemorrhagic stroke.
Traumatic Brain Injury (TBI)
- Focal injuries include contusions and hematomas, while diffuse axonal injury involves shearing of axons.
- Patients can present with conditions such as coma and persistent vegetative state, but the neurotransmitters involved are not specified.
- Treatment includes reducing brain swelling with Mannitol (osmotic diuretic), preventing seizures with Phenytoin (sodium channel blocker), and managing pain and agitation with Opioids and Sedatives.
Myasthenia Gravis
- An autoimmune attack on acetylcholine receptors occurs at the neuromuscular junction.
- Impaired acetylcholine transmission leads to ptosis, diplopia, difficulty swallowing, and muscle fatigue.
- Promotes increased acetylcholine (ACh) levels at the neuromuscular junction by acetylcholinesterase inhibitors.
- Strategies to suppress the immune system include corticosteroids and plasmapheresis/IV immunoglobulin (IVIG) to remove harmful antibodies, especially used in myasthenic crisis.
Guillain-Barré Syndrome (GBS)
- An autoimmune demyelination of PNS triggered by infection where the neurotransmitters involved are not specified.
- Ascending muscle weakness, paralysis, and absent reflexes are typical.
- IVIG or plasmapheresis suppresses the immune response by removing autoantibodies
- Supportive care involves mechanical ventilation if respiratory muscles weaken and pain management using Gabapentin or Pregabalin.
