presentation due to variable involvement of the left, right, dorsal and ventral parts of the …

Diagnostic criteria for a progressive dysexecutive syndrome due to Alzheimer's disease
(dAD) were proposed. Clinical observations suggest substantial variability in the clinico …

The clinical presentation of Alzheimer's disease (AD) varies widely across individuals but
