Effective Communication Strategies for Individuals with Cognitive Impairment: Alzheimer's, Dementias, and FASD

This podcast episode, presented by Dr. Dawn Elise Snipes, provides a comprehensive overview of cognitive impairment, focusing on Alzheimer's disease, various dementias, and Fetal Alcohol Spectrum Disorders (FASD). It begins by defining cognitive deficits such as memory impairment, aphasia, apraxia, agnosia, and executive functioning disturbances, distinguishing these from normal aging processes by emphasizing the degree and progression of symptoms. The discussion highlights diverse causes of cognitive impairment, including Wernicke-Korsakoff syndrome, vascular dementia, brain injuries, and the significant role of uncontrolled type 2 diabetes, particularly recurrent hypoglycemic episodes leading to neurotoxic cortisol release.

The episode delves into screening for cognitive impairment, noting tools like the AD8 and Mini-Cog, and stresses the importance of screening when concerns arise from patients or family, or when observing changes in memory or thinking, regardless of age. It challenges the misconception that dementia is exclusive to those over 65, addressing early-onset and frontotemporal dementias. Key risk factors are explored, including advanced age, low education levels, history of type 2 diabetes or stroke, and depression, with a particular emphasis on how sustained depression, especially melancholic types, significantly increases dementia risk.

Practical management strategies are a core focus, advocating for patient and family education on illness prognosis, treatment options, and the necessity of financial and legal planning. Behavior-oriented treatments are introduced to understand and modify problematic behaviors by identifying their antecedents and consequences, recognizing that behavior often communicates unmet needs. Stimulation-oriented therapies (recreational, art, music, pet therapy) and emotion-oriented treatments like supportive psychotherapy and reminiscence therapy are recommended to maximize well-being and address emotional loss, with a crucial distinction made for reminiscence therapy to avoid putting individuals on the spot.

The episode concludes with actionable communication techniques, emphasizing the importance of patience, anticipation, and avoiding agitation. Strategies include using simple language, speaking slowly, asking direct yes/no questions, breaking down instructions, and utilizing visual aids like picture books, posted lists, and storyboards. The role of assistive devices (glasses, hearing aids) is highlighted, along with the importance of establishing rapport, maintaining eye contact, and optimizing environmental factors like lighting to support effective interaction and reduce confusion, particularly for individuals experiencing sundowning.

"the development of multiple cognitive deficits manifested by both memory impairment and/or aphasia which is a language disturbance apraxia which is the inability to carry out motor activities despite intact motor function agnosia which is failure to recognize or identify objects despite intact sensory function and/or disturbance in executive functioning such as planning organizing sequencing and abstracting"

"what we see in normal aging versus dementia is a matter of degree"

"the earlier we can provide some supportive interventions the better chance we have to delay the progression of the disease"

"depression people with depression show a higher level of cortisol in their system and people with depression I believe are it's like 40% more likely to develop dementia then people who don't have depression"

"behavior has meaning and a lot of people with cognitive impairments especially advanced cognitive impairments may not be able to communicate what their needs are or what's wrong"

"reminiscence therapy helps bring those positive memories to the forefront because a lot of people with cognitive impairment they can't remember things in the recent past"

"people with cognitive impairment are almost never trying to do something to be contrary they are inability to they are unable to communicate what their needs are and they're trying to communicate to you"

"hearing loss in older in old age is also associated with the onset of dementia and it could be because and that's not true of people who are born deaf or who are deaf from an early age"

"don't give people multi-part instructions if they've got cognitive impairment ask them one thing at a time"

"use simple language and speak slowly and distinctly it's harder for them to process as we get older"
