Dementia

Dementia is a broad clinical syndrome characterized by a chronic, progressive decline in cognitive function beyond what is expected from biological aging. It involves impairment in memory, attention, language, executive function, and visuospatial skills, sufficient to interfere with daily social or occupational functioning.

Etiology is multifactorial, including neurodegenerative diseases (Alzheimer’s, Lewy Body), vascular compromise (multi-infarct), traumatic brain injury, chronic substance use, and metabolic/infectious etiologies (e.g., HIV-associated neurocognitive disorder).

Pathophysiology varies by subtype. Common mechanisms include extracellular amyloid-beta plaque deposition, intracellular hyperphosphorylated tau protein tangles, neuroinflammation, cholinergic deficits, and microvascular white matter ischemia leading to neuronal apoptosis and synaptic loss.

Global prevalence exceeds 50 million, doubling every 20 years. Incidence rises sharply after age 65, with women at slightly higher risk than men for Alzheimer-type dementia.

Age, family history (APOE-e4), hypertension, diabetes, smoking, midlife obesity, sedentary lifestyle, depression, social isolation, and low educational attainment.

A. Early Symptoms: Short-term memory lapses, word-finding difficulties, difficulty planning/organizing, disorientation to time.
B. Common Symptoms: Personality changes, impaired judgment, mood swings, wandering, repetition of questions.
C. Advanced Symptoms: Complete loss of verbal communication, inability to perform basic ADLs (bathing, feeding), gait disturbances, incontinence.
D. Emergency Symptoms: Sudden delirium, acute agitation, unresponsiveness, stroke-like focal deficits.

Generally unremarkable early on. Late stages reveal motor deficits, primitive reflexes (grasp, snout), rigidity, and nutritional deficiencies.

A. Clinical Assessment: MMSE, MoCA, Clock Drawing Test.
B. Laboratory Testing: Rule out B12 deficiency, thyroid dysfunction, syphilis.
C. Imaging Studies: MRI/CT for atrophy; PET for metabolic activity.
D. Functional Tests: ADL/IADL scales.
E. Biopsy Findings: Rare; usually post-mortem.
F. Genetic Testing: APOE genotyping.
G. Differential Diagnosis: Delirium, depression (pseudodementia), normal pressure hydrocephalus.

Complete Blood Count
Type: Blood Test
Purpose: Screen for anemia/infection.
Expected Findings: Normal.
Interpretation: Abnormalities suggest secondary causes.

MRI Brain: Assess hippocampal atrophy and ventricular enlargement (Alzheimer's) or microvascular burden (Vascular Dementia).
FDG-PET: Detects hypometabolism in temporoparietal regions.

Delirium (acute/fluctuating), Depression (reversible cognitive slowing), Mild Cognitive Impairment (less impairment in ADLs).

Aspiration pneumonia, pressure ulcers, falls/fractures, malnutrition, secondary infections.

A. Lifestyle Modifications: Cognitive stimulation, physical exercise, Mediterranean diet.
B. Preventive Measures: BP management, smoking cessation.
C. Medical Treatment: - Cholinesterase Inhibitors (Donepezil, Rivastigmine): Increase acetylcholine.

• NMDA Antagonists (Memantine): Regulate glutamate.

Generally progressive and irreversible. Life expectancy varies based on subtype and age at onset, typically 4–10 years post-diagnosis.

Cognitive training, cardiovascular health maintenance, social engagement.
