Chapter 15: Neurocognitive Disorders Flashcards
Neurocognitive Disorders
- affect learning, memory, and consciousness
- develop later in life
- some urinary tract infections can cause symptoms
Types of Memory (3)
Episodic: things that have been experienced, have autobiographical quality
Semantic: facts that aren’t directly related to oneself (think school textbooks)
Procedural: motor skills
Delirium
characterised by impaired consciousness and cognitions lasting several hours or days
- disorientation, out of touch with reality
- attention cannot be maintained
- impairments in memory/language
Delirium Prevalence
- mostly older adults, cancer patients, those with AIDS, and those undergoing medical procedures
- 40-50% of people with Delirium die within 1 year
Delirium Etiology
- intro of drugs/poisons into the body
- e.g. molly and bathsalts
- older adults are bad at getting rid of drugs
- experienced by children with fevers or on certain medications; often confused with noncompliance
- happens during dementia
- withdrawal of anxiolytic drugs
- infection
Delirium Treatments
- addressing the underlying causes first
- antipsychotics
- psychosocial intervention (having familiar objects and family around)
- keeping the patient as independent and in control as possible
Delirium Prevention
- proper care for medical illnesses
- therapeutic drug monititoring
- Multidisciplinary interventions
- reorienting the patient, getting sensory aids, increased sleep, hydration and nutrition, etc
Major and Mild Neurocognitive Disorder
major: formerly called dementia
mild: classification for early stages of cognitive decline
Major and Mild Cognitive Disorder Types (13)
- due to Alzheimer’s
- due to frontotemporal damage
- with Lewy Bodies (motor control dysfunction is highly significant)
- vascular (anything doing with the arteries and blood flow)
- due to traumatic brain injury
- induced by substance or medication
- due to HIV
- due to prion disease
- due to Parkinson’s
- due to Huntingson’s
- due to another medical condition
- due to multiple etiologies
- unspecified
Major and Mild Neurocognitive Disorder Etiologies
- deterministic and susceptibility genes
- substance abuse
- lifestyle choices
- cultural factors
Major and Mild Neurocognitive Disorder Prevalence
1/25 for 65+
1/5 for 85+
5 million Americans
> common for < educated
> common for women
Course of Major and Mild Neurocognitive Disorder
- early onset: 40-50
- usual onset: 60-70s
- memory and visuospatial impairment
- facial agnosia (inability to recognise familiar faces)
- delusions, apathy, depression, agitation, aggression
- early stages/late stages are slow but the middle stages are rapid
- 50% are due to Alzheimers
Different Symptoms (3)
- aphasia
- apraxia
- agnosia
Aphasia
