Detection of adult attention deficit hyperactivity disorder with cognitive complaint: Experience of a French memory center.

Introduction: Attention deficit hyperactivity disorder (ADHD) is a frequent neurodevelopmental mental disorder. It can persist in adulthood and be expressed as a cognitive complaint.

Methods: We conducted a descriptive study in a French memory center concerning patients seen over a period of two years.

Evolution of clinical and electrophysiologic data in patients with a preexcitation syndrome.

Unlabelled: The purpose of the study is to report the natural changes of preexcitation syndrome (PS).

Methods: Electrophysiologic study was performed for syncope (n = 8), atrioventricular reentrant tachycardia (AVRT) (n = 42), atrial fibrillation (n = 3), adverse presentation (n = 4), or for asymptomatic PS (n = 22) and was repeated 1 to 21 years later.

Results: Clinically, 12 patients initially asymptomatic became symptomatic (54.

Patterns of autobiographical memory impairment according to disease severity in semantic dementia.

Studies of autobiographical memory in semantic dementia (SD) have yielded either a reversed temporal gradient or spared performances across the entire lifetime. This discrepancy might be owing to the fact that these studies did not take into account disease severity. Our aim was to study patterns of autobiographical memory impairment according to disease severity and to unravel their mechanisms in 14 SD patients, using an autobiographical memory task assessing overall and strictly episodic memories across the entire lifetime.

Neuropsychological and 18FDG-PET studies in a family with idiopathic basal ganglia calcifications.

Idiopathic basal ganglia calcification (FIBGC) is a rare autosomal dominant neurodegenerative disease, the main clinical signs of which are parkinsonism, cognitive deterioration and/or psychiatric troubles. Familial forms are rare. The underlying basis is not known.

Autonoetic consciousness in Alzheimer's disease: neuropsychological and PET findings using an episodic learning and recognition task.

Objective: This study aims to map in patients with mild Alzheimer's disease (AD) the correlations between resting-state brain glucose utilization measured by FDG-PET and scores reflecting autonoetic consciousness in an episodic learning and recognition task.

Methods: Autonoetic consciousness, that gives a subject the conscious feeling to mentally travelling back in time to relive an event, was assessed using the Remember/Know (R/K) paradigm.

Results: AD patients provided less R responses (reflecting autonoetic consciousness) and more K ones (indicating the involvement of noetic consciousness) than healthy controls.
