Examining older adults with neuroatypical conditions for MCI/dementia: Barriers and recommendations of the Neuroatypical Conditions Expert Consultative Panel

The Neuroatypical Conditions Expert Consultative Panel composed of numerous clinical and academic experts was convened to examine barriers to the examination of cognitive impairment in adults with a variety of neuroatypical conditions. Neuroatypical conditions affect normative intellectual development and function (such as intellectual disability and intellectual disability with conjoint psychiatric conditions), thought, moods, and cognition (such as severe mental illness), communication functions (such as the autism spectrum and hearing/vision impairments), and brain and motor function (such as cerebral palsy and acquired or traumatic brain injury). The panel concluded that current federal guidance for the assessment of cognitive impairment for mild cognitive impairment (MCI) or dementia does not sufficiently include information as to how to assess such adults. In addition, it concluded that adults with these conditions (1) challenge clinicians when attempting to discern current behavior and function from that which was pre-existing; (2) often have inherent comprehension and oral communication difficulties, motor task performance impediments, and difficulty with visuals; and (3) pose difficulties when assessed with standardized dementia measures and can benefit from the use of specialized instruments. The panel recommended that federal guidance be broadened to include adaptations of assessment practices to accommodate neuroatypical conditions; that educational packs be developed for clinicians about such conditions and on detecting and diagnosing MCI or dementia; and that research be expanded to produce more evidence-based information on both assessing adults with neuroatypical conditions for later-life adult cognitive diseases/disorders and planning post-diagnostic care.

Associations of Circulating Insulin-Growth Factor-1 With Cognitive Functions and Quality of Life Domains in Ambulatory Young Adults With Cerebral Palsy: A Pilot Study

Objective

Adults with cerebral palsy (CP) often have impaired cognitive functions. CP also has deteriorations in multiple quality-of-life (QoL) domains. The bio-psycho-social health psychology model posits that biological factor interacts with social and psychological functions. However, the biological determinant of psycho-social and functional outcomes in CP has been scarcely examined. Circulating Insulin-like growth factor-1 (IGF-1) is associated with cognitive deficits in older adults, we thus aimed to examine the associations of circulating IGF-1 with: (1) objectively measured cognitive functions, (2) self-reported cognitive functions, and (3) QoL measures in adults diagnosed with CP.

Methods

Seventy-two adults with CP and varying degrees of cognitive functions were recruited from an accredited clinical motion analysis laboratory at a regional Children's Hospital. Circulating IGF-1 was measured using post-fasting serum. The Wechsler Adult Intelligence Scale (WAIS) tests were administered to assess multiple cognitive functions, whereas the Patient-Reported Outcomes Measurement Information System (PROMIS) was used to measure multiple domains of self-reported health, including cognitive complaints and eight QoL domains.

Results

Sixty-eight participants had complete data [mean age = 25 (SD = 5.3), female = 52.8%]. Controlling for covariates, circulating IGF-1 was associated with multiple cognitive domains, including positively with declarative memory and executive function and inversely with visual-spatial and motor skills, and processing speed, while no association with subjective memory complaint was detected. Circulating IGF-1 was also inversely associated with four QoL domains, including depressive symptoms, executive function, physical function, and social roles and activities.

Conclusions

In CP, circulating IGF-1 might be a useful biological determinant of objective cognitive functions and several quality-of-life domains commonly impaired in CP.

Adults with Cerebral Palsy Require Ongoing Neurologic Care: A Systematic Review

Cerebral palsy (CP) neurologic care and research efforts typically focus on children. However, most people with CP are adults. Adults with CP are at increased risk of new neurologic conditions, such as stroke and myelopathy, that require ongoing neurologic surveillance to distinguish them from baseline motor impairments. Neurologic factors could also contribute to the motor function decline, chronic pain, and chronic fatigue that are commonly experienced by adults with CP. Based on a systematic literature review, we suggest (1) guidelines for neurologic surveillance and neurologist referral and (2) clinical research questions regarding the evolving neurologic risks for adults with CP.
