متلازمة الفص الجبهي : دراسة نفسية عصبية لوظيفتي الانتباه الانتقائي و الذاكرة العاملة

Abstract EN

The frontal lobe syndrome is the largest of all lobes, it occupieds 1 / 3 of hemisphere which contains five kies areas for neuropsychologyy functions : executive ; intellectual : abstraction & judgment ; emotional behavior & personality ; attention & memory ; language.

The frontal syndrome is a disorder affecting the functional frontal lobe in one area or more of motor cortex: primary motor cortex ; premotor cortex; supplementary motor ; frontal eye field ; Broca’s speech area , or in prefrontal cortex: areas orbital prefrontal cortex ; dorsolateral prefrontal cortex ; dorsomedial prefrontal cortex.

The syndrome needs rigorous testing strategies to probe frontal functions.

In absence of neuropsychological treatment, the syndrome slows down the psychomotor activities such as a loss of initiatives and necessary actions in daily and social life.

The study contributes to the description, diagnosis and interpretation of selective attention and working memory processes in frontal lobe syndrome, and which type of working memory is more affected, then, the relationship between the selective attention and working memory and their mechanism processes deficit on using the clinical method in neuropsychology clinical assessment.

The study found a deficit in selective attention with slow responses caused by the stimulus interference and the executive center of memory is more affected because the attentional control is on dysfunction (Baddely).

The mechanism of attention uses the sensory register of working memory to ensure its function, and some mechanisms of working memory control the processes of attention.

Then, more the executive center is on deficit, the selective attention is involved.
