RESUMO
The scientific literature on neuropsychological correlates of Mild Cognitive Impairment of the Amnestic Type (MCI-A) often reports large group findings and employs multivariate statistics to describe domains of cognitive impairment associated with the transition of MCI-A to early dementia, typically of the Alzheimer's Type (AD). Individual patients may vary, however, in terms of specific changes in their neuropsychological test performance as they transition from MCI-A to probable AD. The subjective experiences of individuals during this time of transition can also vary but rarely are reported. Tracking both the patient's subjective experiences and their performance on neuropsychological measures provides a more complete picture of the patient's clinical situation. These combined sets of information help the clinical neuropsychologist provide a more individualized and personally relevant service. We present a phenomenological and neuropsychological case analysis of a 67-year-old woman who transitioned from MCI-A to probable early AD in an attempt to illustrate how such a combined analysis is helpful in their psychological care.
RESUMO
The cause(s) of lack of awareness of cognitive decline in neurodegenerative diseases can be multifactorial. Yet neurologically oriented research on anosognosia of cognitive decline almost exclusively assumes that the underlying disturbance of neuro-networks that support various cognitive functions accounts for the reduced self-awareness. Cultural and psychosocial factors, including the person's emotional state, however, can contribute to the underreporting or avoidance of admitting to cognitive impairments in neurodegenerative diseases. Research on the causes of lack of awareness of cognitive decline in neurodegenerative disorders needs to include these variables. We briefly present two case examples of underreporting or "unawareness" of memory difficulties in persons with mild cognitive impairment (MCI) (or minor neurocognitive disorder). One presented with classic anosognosia for memory impairment, while the other initially reported no memory impairment but later admitted to "denying" her memory difficulties secondary to anxiety. Based on these patients' clinical presentations and available research, we suggest three potential screening items that may help identify probable denial of memory impairments when studying anosognosia in MCI.
