Two distinct subtypes of right temporal variant frontotemporal dementia.

Nov 2009 BACKGROUND: Right temporal frontotemporal dementia (FTD) is an anatomic variant of FTD associated with relatively distinct behavioral and cognitive symptoms. We aimed to determine whether right temporal FTD is a homogeneous clinical, imaging, and ... Read more...

Global perception in simultanagnosia is not as simple as a game of connect-the-dots.

17 May 2009 Simultanagnosia is a neuropsychological disorder characterized by a restriction of visuospatial attention. In addition, patients are able to identify local elements of a scene, but not the global whole. This may be due to a failure to scan and ... Read more...

The anatomy of object recognition--visual form agnosia caused by medial occipitotemporal stroke.

4 May 2009 The influential model on visual information processing by Milner and Goodale (1995) has suggested a dissociation between action- and perception-related processing in a dorsal versus ventral stream projection. It was inspired substantially by the ... Read more...

Technical information about 'Agnosia'

Definition: Loss of the ability to comprehend the meaning or recognize the importance of various forms of stimulation that cannot be attributed to impairment of a primary sensory modality. Tactile agnosia is characterized by an inability to perceive the shape and nature of an object by touch alone, despite unimpaired sensation to light touch, position, and other primary sensory modalities.
