The primary purpose of the study was to compare the results of neuropsychological assessments with results obtained using a translated Cognitive Change Index (CCI) on patients with diagnosed brain pathology. Our study included 54 patients diagnosed with neurologic pathology (stroke, TBI, or brain tumor) at the University Rehabilitation Institute Soca (average age = 51 years, SD = 15 years). The results of neuropsychological evaluations and anamnestic data were also obtained for the clinical subsample. Confirmatory factor analysis of the translated CCI performed on responses of 151 normative elderly participants supported a one-factor structure of the questionnaire. Cronbach's α was 0.77 in the clinical sample. A significant correlation was found between lower scores for attention and visual abilities using objective measurement tools and a person's self-assessment of impairment in their own cognitive functions (score on CCI). Individuals can perceive that their attention and visual abilities are impaired when those abilities also score low in diagnostic tests.

Prader-Willi syndrome is a rare neurodevelopmental disorder that impacts the musculoskeletal, endocrine, pulmonary, neurologic, ocular, and gastrointestinal systems. In addition, individuals with Prader-Willi syndrome have issues with cognitive development, characteristic behavioral problems, and perhaps most profoundly, appetite control. Currently, the only US Food and Drug Administration-approved therapy for Prader-Willi syndrome is growth hormone, which has been Food and Drug Administration approved for > 20 years for the treatment of growth failure in Prader-Willi syndrome.

In Alzheimer's disease (AD), the accumulation of neuropathological markers such as amyloid-β plaques, neurofibrillary tangles, and cortical neurodegeneration occurs over many years before overt manifestation of cognitive impairment. There is thus a need for neuropsychological markers that are indicative of pathological changes in the early stages of the disease. Intra-individual cognitive variability (IICV), defined as the variation of an individual's performance across cognitive domains, is a promising neuropsychological marker measuring heterogeneous changes in cognition that may reflect these early pathological changes.

EEG involves recording electrical activity generated by the brain through electrodes placed on the scalp. Imagined speech classification has emerged as an essential area of research in brain-computer interfaces (BCIs). Despite significant advances, accurately classifying imagined speech signals remains challenging due to their complex and non-stationary nature.
