Effect of cognitive fluctuation on handwriting in alzheimer's patient: a case study

Introduction: The older population is rapidly growing in the European states and across the globe; and in aging we notice a cognitive declines, a decrease in memory and decision-making abilities. Characteristics of the cognitive fluctuations occur infrequently in the elderly, but they are present in patients with dementia. Fluctuating cognition and abilities have been described as periods of behavioral and thought confusion, inattention, and incoherent speech alternating with episodes of lucidity. It is common in Dementia with Lewy bodies (DLB), however, the role of fluctuations in Alzheimer’s disease (AD) has not been much considered. Case presentation: The present study examines the relationship between cognitive status and handwritten scripts, presented as ‘letter-writing’ in AD patient, as oscillations of the symptoms phase. Discussion: We present evidence that the deficits of attention and its fluctuations and the cognitive impairment are related with the handwritten expression.
