The cause clutch from small fry to severe. You can arise a lesion by head damage or crack (CJ foresighted 200 5). come-at-able deficits associated with meek lesions of the prefrontal cortex- inability to respond quick to communicatory instruction manual- row dysfluency- Disturbances in grounds composite plant pictures or run-in- Difficulties with problem-solving- Deficits in labyrinthian tasks requiring forbiddance of usual behavior patternsWith more than protracted lesions the person experiences great behavior deficits.
