Symptoms
Patients with utilization behavior feel they are functioning normally and do not believe that their actions are anything out of the ordinary. Sufferers are unable to resist grasping or using an object placed in front of them, regardless of the context or environment. It is not known what triggers them to exhibit UB with certain external stimuli and not others.
A disorder related to UB consists of the feeling that a body part is separate from the rest of the body and has a mind of its own. The patient does not recognize the limb as one that he/she owns and believes it to be a foreign object which he cannot control. This set of symptoms is related to Alien hand syndrome (AHS), a neurological disorder in which the subject does not acknowledge ownership of a limb when visual cues are lacking. AHS can involve damage to the anterior cingulate gyrus, the medial prefrontal cortex and the anterior corpus callosum when a patient has frontal AHS. The other type of AHS, Callosal AHS, is due to an anterior callosal lesion and affects dominant hemisphere control.

Famous quotes containing the word symptoms:
“In retirement, only money and symptoms are consequential.”
—Mason Cooley (b. 1927)
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“A certain kind of rich man afflicted with the symptoms of moral dandyism sooner or later comes to the conclusion that it isn’t enough merely to make money. He feels obliged to hold views, to espouse causes and elect Presidents, to explain to a trembling world how and why the world went wrong. The spectacle is nearly always comic.”
—Lewis H. Lapham (b. 1935)
