What are the features of cortical dementia?
Cortical release signs Language impairment - Aphasia Perseveration Disinhibition Memory impairment Agnosia Apraxia Impaired visuospatial construction
What anatomic loci is cortical dementia associated with?
Neocortical association areas
Hippocampus
What are the features of subcortical dementia?
Slowing in information processing Reduced attention Poor executive function Poor visuospatial function Emotional lability Motor signs: pyramidal or extrapyramidal
What anatomic loci is subcortical dementia associated with?
Thalamus
Basal ganglia
Rostral brain stem
What are cortical dementias?
Alzheimer’s
FTD
Pick’s disease
What are subcortical dementias?
Parkinson's disease Huntington disease Wilson disease AIDS dementia Progressive supranuclear palsy
Which are mixed dementias?
Vascular dementia
Creutzfeldt-Jakob disease
Dementia due to trauma
What are the main features of lewy body dementia?
Dementia visual hallucinations parkinsonism cognitive fluctuations dysautonomia sleep disorders neuroleptic sensitivity
In addition to dementia, a patient with probable DLB must have at least two “core clinical features” of DLB: cognitive fluctuations, visual hallucinations, rapid eye movement (REM) sleep behavior disorder (RBD), and parkinsonism
What are pathological findings in Lewy Body Dementia?
pathologic hallmark of DLB is the presence of eosinophilic intracytoplasmic inclusions called Lewy bodies, which contain aggregated alpha-synuclein, in the deep cortical layers throughout the brain, especially in anterior frontal and temporal lobes, cingulate gyrus, and insula.
Ddx for falls with cognitive impairment?
Delirium
NPH
Li toxicity
Early features for DLB?
DLB is characterized by early impairments in attention and executive and visuospatial function, with memory affected later in the course of the disease [3-9]. Early symptoms include driving difficulty (eg, getting lost, misjudging distances, or failing to see stop signs or other cars) and impaired job performance.
