Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production.
Hypofrontality is a symptom of numerous neurological diseases defined as reduced utilization of glucose and blood flow in the prefrontal cortex. Hypofrontality can be difficult to detect under resting conditions, but under cognitive challenges, it has been seen to correlate with memory deficits along with executive function deficits.
The symptoms observed in bvFTD are caused by dysfunction of the orbitofrontal cortex; thus these two neuropsychological tests might be useful in detecting early-stage bvFTD. However, as self-monitoring and somatic marker processes are so complex, it likely involves other brain regions.
The prefrontal cortex has been defined based on cytoarchitectonics by the presence of a cortical granular layer IV.It is not entirely clear who first used this criterion. Many of the early cytoarchitectonic researchers restricted the use of the term prefrontal to a much smaller region of cortex including the gyrus rectus and the gyrus rostralis (Campbell, 1905; G. E. Smith, 1907; Brodmann ...
The cerebellum is also responsible for refining crude motor output from the primary motor cortex. When this refinement is missing, symptoms such as unsteadiness and ataxia [8] will present. A potential cause of chronic alcoholic cerebellar dysfunction is an alteration of GABA-A receptor.
