Study Notes
Alzheimer's Disease
- Characterized by memory loss
- Symptoms:
- Forgetting names and places
- Asking questions repeatedly
- Poor judgment
- Amyloid plaques accumulate outside the neurons
- Tau protein accumulates inside the neurons
- Cell death occurs, leading to memory loss
Parkinson's Disease
- Characterized by low dopamine levels
- Symptoms:
- Tremors
- Bradykinesia (slow movement)
- Difficulty speaking
- Dopamine neurotransmitter reduction leads to degradation of dopaminergic neurons
Epilepsy
- Brain disorder characterized by seizures
- Symptoms:
- Seizures
- Body stiffness
- Loss of consciousness
- Abnormal electric activity in the brain causes nerve excitation
Depression
- Mental disorder characterized by sadness and loss of interest in activities
- Symptoms:
- Low mood
- Sadness
- Low self-esteem
- Lack of interest and motivation
- Suicide tendency
- Depletion of serotonin, norepinephrine, and dopamine in the brain
Schizophrenia
- Mental disorder characterized by hallucinations and delusions
- Symptoms:
- Hallucinations
- Delusions
- Social isolation
- Imbalance of dopamine, serotonin, glutamate, and GABA
Stroke
- Block of blood oxygen supply to the brain
- Symptoms:
- Numbness in the face
- Trouble speaking
- Trouble in vision
- Vertigo
- Ischemic Stroke: Caused by blood vessel blocking (e.g., thrombus formation)
- Hemorrhagic Stroke: Caused by blood vessel rupture
Meningitis
- Infection and inflammation of the fluid and meninges surrounding the brain and spinal cord
- Symptoms:
- High temperature
- Stiff neck
- Seizures
- Infection in the meninges caused by bacteria or viruses
Shingles
- Viral disease characterized by a painful skin rash with blisters in a localized area
- Symptoms:
- Burning pain
- Red rash
- Itching
- Infection of neurons by varicella zoster virus
Peripheral Neuropathy
- Damage to the peripheral nerves
- Symptoms:
- Numbness and weakness, especially in the hands and feet
- Caused by infections, toxins, and diabetes
- Neuron damage
Myasthenia Gravis
- Muscle weakness due to a problem between the nerves and the muscles
- Symptoms:
- Drooping of one or both eyelids
- Difficulty swallowing
- Autoimmune disease
- Autoantibodies attack the nicotinic receptors on the muscles
