A professional musician with progressive visuospatial concerns: a case study and review of musical alexia.

This case report presents the story of Mr. S, a professional orchestral musician with declining musical sight-reading ability, followed by progressive visuospatial and language deficits. Our novel musical assessment battery revealed deficits in music-reading (musical alexia) and music-writing (musical agraphia), with spared auditory perception and expression.

Medial Amygdalar Tau Is Associated With Mood Symptoms in Preclinical Alzheimer's Disease.

Background: While the amygdala receives early tau deposition in Alzheimer's disease (AD) and is involved in social and emotional processing, the relationship between amygdalar tau and early neuropsychiatric symptoms in AD is unknown. We sought to determine whether focal tau binding in the amygdala and abnormal amygdalar connectivity were detectable in a preclinical AD cohort and identify relationships between these and self-reported mood symptoms.

Methods: We examined 598 individuals (347 amyloid positive [58% female], 251 amyloid negative [62% female] subset in tau positron emission tomography and functional magnetic resonance imaging cohorts) from the A4 (Anti-Amyloid Treatment in Asymptomatic AD) Study.

Medial amygdalar tau is associated with anxiety symptoms in preclinical Alzheimer's disease.

Background: While the amygdala receives early tau deposition in Alzheimer's disease (AD) and is involved in social and emotional processing, the relationship between amygdalar tau and early neuropsychiatric symptoms in AD is unknown. We sought to determine whether focal tau binding in the amygdala and abnormal amygdalar connectivity were detectable in a preclinical AD cohort and identify relationships between these and self-reported mood symptoms.

Methods: We examined n=598 individuals (n=347 amyloid-positive (58% female), n=251 amyloid-negative (62% female); subset into tau PET and fMRI cohorts) from the A4 Study.
