Study Notes

Neuropsychiatric Symptoms of Dementia

Behavioral and Psychological Symptoms of Dementia (BPSD) involve disturbed perception, thought, mood, or behavior. Symptoms can occur separately or cluster together.
Common clusters include agitation, psychosis, and mood disorders.
Neuropsychiatric Inventory (NPI) is a semi-structured instrument for caregivers to assess symptoms.
The NPI rates symptoms based on frequency, severity and overall severity.
The NPI uses 12 domains for evaluation.

Mild Cognitive Impairment (MCI)

Neuropsychiatric symptoms are present in 25% of individuals with MCI.
Symptoms are persistent for at least 6 months.
Persistent symptoms like delusions, agitation, apathy, and sadness are often found to be more severe in MCI at the baseline.

Pre-cognitive Impairment

New neuropsychiatric symptoms can appear in older adults without cognitive impairment, potentially indicating pre-dementia.
New-onset agitation is strongly associated with a higher risk (odds ratio) of developing MCI over 5 years.
Neuropsychiatric symptoms (NPS) in pre-dementia are linked to factors like tau and amyloid neuropathology.
Underlying neurobiological mechanisms are suggested to play a role, as are genetics, personal history, comorbidities, environment, and caregiver response.

Prevalence of NPS in Dementia

75% of people with Alzheimer's Disease (AD) experience at least one clinically significant symptom.
80% have persistent symptoms for 6 months.
Common persistent symptoms are apathy, aberrant motor behaviors, and agitation.
The persistence of symptoms is linked to their severity at the initial assessment.
In nursing homes, over 90% of patients exhibit one or more significant neuropsychiatric symptoms, and these tend to persist.

Psychosis in Dementia

Prevalence of psychosis in dementia is approximately 18% in cross-sectional studies.
Prevalence increases with the progression to moderate dementia, and then plateaus.
Psychotic symptoms often persist for many months.
Delusions (false beliefs) are a common type of psychotic symptom, often simple in nature (theft, abandonment, poisoning, misidentification).
Hallucinations (perceiving something that isn't there) frequently involve visual perceptions. Auditory hallucinations (sounds, individual words) can also occur, and are especially prevalent in Dementia with Lewy Bodies (DLB). Hallucinations are less common in Frontotemporal Dementia (FTD).
Charles Bonnet Syndrome (CBS) is a condition involving complex, persistent visual hallucinations in visually impaired individuals without other mental health conditions..

Depression in Dementia

Depression affects at least 20% of people with dementia, particularly in Vascular Dementia.
Medications and psychotherapy alone may not be effective in treating depression in dementia.

Interventions that show Effectiveness

Interventions during the initial phase of neuropsychiatric symptoms include activities, music therapy, and sensory interventions.
Over time, supervised person-centered care, communication skills training, and tailored activity programs are helpful, along with carer education and stress reduction techniques.

Interventions that are NOT effective

Light therapy and aromatherapy are not consistently effective interventions for neuropsychiatric symptoms in dementia.

Sleep Disturbances in Dementia

Sleep disturbances are common in dementia (39% in AD, higher in DLB)
Symptoms include impaired sleep initiation and quality (reduced nighttime sleep) and daytime sleep.
Nighttime wandering and behavioral changes during sleep are also observed.
Sleep problems are often linked to disruptions in the normal circadian rhythm, as well as other factors such as inactivity/napping disrupting sleep pressure, and underlying medical conditions, environmental factors and stress.
