Key Points: Disorders of Nervous System

Two types — Psychological (mental, affects mood/thinking/behaviour) and Neurological (damage/malfunction of the nervous system).
Psychological Disorders — Examples: ADHD, Anxiety, Depression, Bipolar Disorder, ASD, Intellectual Disability.
Neurological Disorders — Examples: Alzheimer's and Parkinson's disease.
Parkinson's Disease — Degeneration of dopamine-producing neurons in the CNS. Symptoms: tremors, stiffness, difficulty in walking and balance.
Alzheimer's Disease — Common dementia; memory and cognitive decline. Caused by loss of neurons and amyloid protein accumulation in the CNS.
