Neurological Disorders Quiz

Neurological Disorders

Alzheimer's Disease

• A degenerative brain disease causing memory loss and cognitive decline
• Most common form of dementia (60-80% of cases)
• Characterized by:
  • Amyloid plaques and neurofibrillary tangles in the brain
  • Death of brain cells, leading to brain shrinkage
• Symptoms:
  • Memory loss, confusion, and difficulty with communication
  • Mood changes, personality changes, and behavioral problems
• No cure, but treatments available to manage symptoms

Parkinson's Disease

• A neurodegenerative disorder affecting movement and motor control
• Characterized by:
  • Death of dopamine-producing neurons in the brain
  • Formation of Lewy bodies (abnormal protein clumps)
• Symptoms:
  • Tremors, rigidity, bradykinesia (slow movement), and postural instability
  • Difficulty with balance, coordination, and walking
• No cure, but treatments available to manage symptoms

Multiple Sclerosis (MS)

• A chronic autoimmune disease affecting the central nervous system
• Characterized by:
  • Immune system attacks and damages myelin (protective coating) around nerve fibers
  • Scarring and inflammation leading to communication disruptions between brain and body
• Symptoms:
  • Vision problems, muscle weakness, numbness, and tingling
  • Fatigue, balance problems, and cognitive difficulties
• No cure, but treatments available to manage symptoms and slow disease progression

Epilepsy

• A neurological disorder characterized by recurrent seizures
• Causes:
  • Abnormal electrical activity in the brain
  • Genetic predisposition, head trauma, infection, or unknown
• Symptoms:
  • Seizures, which can vary in severity and impact
  • Confusion, drowsiness, and fatigue following seizures
• Treatment:
  • Medications to control seizures, surgery in some cases

Stroke

• A medical emergency occurring when blood flow to the brain is blocked or reduced
• Causes:
  • Blockage of a blood vessel (ischemic stroke) or rupture of a blood vessel (hemorrhagic stroke)
• Symptoms:
  • Sudden weakness, numbness, or paralysis of the face, arm, or leg
  • Sudden difficulty speaking, understanding speech, or swallowing
• Treatment:
  • Immediate medical attention, including medication and surgery

Autoimmune Neurological Disorders

• Conditions in which the immune system mistakenly attacks and damages the nervous system
• Examples:
  • Multiple sclerosis (MS)
  • Guillain-Barré syndrome
  • Chronic inflammatory demyelinating polyneuropathy (CIDP)
  • Myasthenia gravis
• Symptoms:
  • Vary depending on the specific disorder and affected nerve cells
  • Can include muscle weakness, numbness, tingling, and vision problems
