Objective: To investigate the neural mechanisms that differentiate dressing apraxia from other forms of apraxia such as ideomotor apraxia. Hypotheses examined included (1) that dressing is more sensitive to alternations in body schema, (2) that dressing is a demanding bimanual task, and (3) that clothing represents a particularly complex spatial problem.
Background: A focal degenerative condition can specifically target a function such as dressing, allowing a unique approach to its study.
Method: A case study of the cognitive impairments of a 75-year-old man who presented with progressive dressing difficulties in the absence of neglect or motor disturbances.
Results: Neuropsychologic testing indicated possible executive function deficits as well as visuospatial and visuocontructional deficits, but intact praxic skills, verbal abilities, and visual recognition skills. In addition, testing revealed no evidence of Balint's or impairments in body schema.
Conclusion: Overall, the test results suggested that visuospatial dysfunction is the underlying deficit in dressing apraxia. The present case study confirmed the independence of praxic functioning from spatial ability and conversely, the dependence of dressing on spatial ability.

Article Synopsis
- This study investigated the relationship between tau pathology in specific brain regions and apraxia symptoms in Alzheimer's disease (AD) patients, using PET imaging to assess tau deposition.
- Researchers hypothesized that certain areas with tau buildup would correlate with the severity of apraxia, a common cognitive dysfunction in AD.
- Findings revealed significant correlations between tau aggregation in specific praxis-related brain regions and apraxia severity, while no connections were found in primary motor cortex or subcortical regions.
A case of amusia with beat deafness and apraxia of speech.

Department of Dementia and Neuropsychology, Advanced Institute of Industrial Technology, Tokyo Metropolitan Public University Corporation, Tokyo, Japan.
After experiencing two ischemic brain attacks, a 40-year-old, right-handed, female amateur cello player developed apraxia of speech (AOS) and amusia, especially on the aspect of the beat. Her tempo became gradually faster, but while playing, she could not recognize that. When she listened to her own recorded performances, she could identify the differences immediately and precisely.

Article Synopsis
- Research examined three patients with different types of brain damage over 7 months, focusing on the core symptoms and underlying brain structures related to the syndrome.
- The study found no common areas of grey matter damage among the patients, but identified similar patterns of white matter disconnections affecting communication between brain hemispheres and other areas involved in motor control.

Purpose Of Review: Apraxia typically involves impairments in gesture production and tool use, affecting daily life activities. This article reviews current conceptualizations and developments in diagnostic and therapy.
Recent Findings: Apraxia has been studied in various neurological conditions, particularly stroke and dementia, but recent studies show gesturing deficits in psychiatric populations as well.
