Cognition
Ability of the brain to process, retain, and use information
Delirium definition
Disturbance of consciousness, accompanied by a change in cognition
Delirium is a disturbance in what?
Attention and awareness
What often accompanies a change in cognition?
memory deficit, disorientation, language disturbance
What perceptual disturbances can delirium lead to
Illusions and hallucinations
Symptoms of delirium
- Impaired judgement • Impaired orientation • Memory
- Attention
- Consciousness
- Disorganized thinking
- Perception disturbances
- Change in emotions
- Autonomic manifestations
skim over these
What are autonomic manifestations of delirium?
Tachycardia, sweating, flushed face, dilated pupils, elevated blood pressure
Delirium onset
Develops over a short period of time, usually presents abruptly
Duration is usually brief and subsides completely on recovery from underlying cause
Symptoms usually fluctuate during the day
Treatment of delirium
Corrections of underlying condition to promote recover
What medical conditions might delirium result from?
Infections, febrile illness, metabolic disorders, head trauma, seizures, migraine headaches, brain abscess, stroke, electrolyte imbalance, and others
Describe substance-induced delirium and certain substances that can lead to this.
May be caused by intoxication or withdrawal from certain substances
• Anticholinergics, antihypertensives, corticosteroids, anticonvulsants, analgesics, and others
• Alcohol, amphetamines, cannabis, cocaine, hallucinogens, inhalants, and others • Toxins, including organic solvents and fuels, lead, mercury, arsenic, carbon
monoxide, and others
Delirium tremens
Go back and looks
Delirium treatment
• Underlying causes
• Staff to remain with patient at all times to monitor
behavior and provide reorientation and assurance.
• Room with low stimulus
• Low-dose antipsychotic agents to relieve agitation and aggression
• Benzodiazepines commonly used when etiology is substance withdrawal
Neurocognitive Disorders: Mild (mild cognitive impairment) - brief description
- Early intervention, slow progression
- Modest cognitive decline from previous functioning
- Does not interfere with ADLs
Gradual onset typically, progressive decline
Neurocognitive disorders: Major (Dementia) - brief overview
Significant cognitive decline from previous functioning
Interferes with ADLs
Gradual onset, progressive decline
What is the most common predisposing factor to neurocognitive disorder?
Alzhiemer’s disease (50-80% of all cases)
Neurocognitive disorder may be due to what?
Prion disease, TBI, Lewy body dementia, Parkinson’s disease, HIV, Huntington’s
Primary Neurocognitive Disorder
those in which the disorder itself is the major sign of some organic brain disease not directly related to any other organic illness (e.g., Alzheimer’s disease).
Secondary Neurocognitive disorder
caused by or related to another disease or condition (e.g., H I V disease or cerebral trauma).
MND: Dementia - what?
- Acquired impairment of memory and other intellectual functions of sufficient severity to interfere with social and occupational functioning
- Severe impairment in memory, judgement, orientation, and cognition
- Severity (mild, moderate, severe)
What might someone experience as Dementia progresses?
- Aphasia
- Apraxia
- Irritability and moodiness, with sudden outbursts over trivial issues
- Inability to care for personal needs independently
- Wandering away from the home
- Incontinence
What is reversible neurocognitive disorder, and what is it often a result of?
Temporary dementia
It can occur as a result of: • Stroke • Depression • Side effects of medications • Nutritional deficiencies • Metabolic disorders
Alzheimer’s Disease onset
Slow, insidious onset. Typically runs a progressive, irreversible course with continuing cognitive decline and behavioral symptoms
7 stages
7 stages of Alzheimer’s disease
- No apparent s/s
- Forgetfulness
- Mild cognitive decline
- Mild-to-moderate cognitive decline
- Moderate cognitive decline
- Moderate to severe cognitive decline
- Severe cognitive decline
