tests, as well as concurrent findings from several measures designed to directly assess malingering (Dot Counting [M. D. Lezak, 1983] and 15-Item Memorization Tests [Lezak, 1983] and the Credibility Scale [P. R. Lees-Haley, 1990]) suggested a pattern of exaggeration of cognitive symptoms. ...
Differential diagnosis is a process of ruling out health conditions that resemble your symptoms. A healthcare provider will likely order lab tests based on yourhealth history, physical exam, and symptoms. They may conduct a mental health screening to check for mood disorders like anxiety and depres...
Consequently, neurodevelopmental prediction studies have used resting-state functional connectivity (resting FC) to predict individual differences in cognitive performance18,19, impulsivity scores20 and autism symptoms21,22. Recent studies have further suggested that task-state functional connectivity (task FC...

Lesions can be surgically removed from the brain in some patients, she added. For others, only the symptoms can be treated. The team will next seek out the last of the genes known to cause CCM, Marchuk said. The investigators have also begun exploring thebiological basis of CCM in mice ...
