Cognitive Disorders

Cognitive disorders involve decline in memory, thinking, attention, and executive function, affecting independence and daily functioning. Major disorders include delirium and dementia, with key exam focus on acute vs chronic onset, reversibility, causes, safety, and nursing care. These conditions are common in older adults and require early recognition, monitoring, and supportive care.

1️⃣ Overview of Cognitive Disorders

🧠 Core Pattern

🔷 Cognitive disorders → decline in memory, thinking, reasoning, awareness

🔷 Affect attention, perception, language, executive function abilities

🔷 Cause functional impairment → ADLs, safety, decision-making ability

🔷 May be acute (delirium) or chronic progressive (dementia types)

🔷 Often multifactorial → medical illness, medications, neurologic disease

🔷 Early recognition critical to prevent complications and deterioration

🔎 Assessment Findings

🔷 Memory loss, confusion, disorientation, impaired judgment, attention deficits

🔷 Changes in personality, mood, behavior, communication abilities

🔷 Difficulty performing familiar tasks or following simple instructions

🔷 Altered level of consciousness in acute conditions like delirium

🔷 Assess baseline cognition versus current status for accurate comparison

🔷 Use tools → MMSE, MoCA, CAM for structured cognitive assessment

💊 Management

🔷 Identify and treat underlying cause if reversible condition present

🔷 Medications PRN → cholinesterase inhibitors, memantine for dementia

🔷 Avoid polypharmacy → review medications contributing to confusion

🔷 Supportive care → hydration, nutrition, sleep, sensory correction

🔷 Environmental modification → reduce confusion, promote orientation

🔷 Interdisciplinary care → neurology, geriatrics, psychiatry involvement

🩺 Nursing Priorities

🔷 Monitor cognitive changes and progression closely over time

🔷 Ensure patient safety → falls, wandering, medication adherence

🔷 Provide structured routine and familiar environment consistently

🔷 Use simple communication and reorientation techniques

🔷 Support family and caregiver education

🔷 Document changes and response to interventions accurately

2️⃣ Delirium

🧠 Acute Confusion

🔷 Delirium → acute, fluctuating disturbance in attention and awareness
