“is a slowly progressive disease of the brain that is characterized by impairment of memory and eventually by disturbances in reasoning, planning, language, & perception”
Generally diagnosed in people over 65 years of age -Early-onset (before 65); only 5-10% of patients 4.5+ million Americans suffer from it 1 in 6 women over 55 1 in 10 men over 55
Idiopathic Cholinergic hypothesis -Caused by reduced synthesis of acetylcholine -Destruction of these neurons causes disruptions in distant neuronal networks (perception, memory, judgment) Amyloid hypothesis -Abnormal breakdown; buildup of amyloid beta deposits -Damaged amyloid proteins build to toxic levels, causing call damage and death Genetics
Obesity High blood pressure Head trauma High cholesterol Depression Lower rates in highly educated Family history
Due to etiological factor Amyloidosis ( Amyloid Decreased production of acetylcholine preserved protein deposition in neurone) Memory loss, Forgetfulness, Depression, Loss their familiar Phases, Place, Object & Environment

History Physical examination (MSE) Mental State Examination (used to evaluate the cognitive impairments) C.T Scan MRI PET
