Neuroanatomical evidence
Bálints syndrome has been found in patients with bilateral damage to the posterior parietal cortex. The primary cause of the damage and the syndrome can originate from multiple strokes, Alzheimers disease, intracranial tumors, or brain injury. Progressive multifocal leukoencephalopathy and Creutzfeldt–Jakob disease have also been found to cause this kind of damage. This syndrome is caused by damage to the posterior superior watershed areas, also known as  the parietal-occipital vascular border zone (Brodmanns areas 19 and 7). Manifestations
Some telltale signs suggesting Bálints syndrome following bilateral brain insults may include:
limitation to perceive only stimuli that is presented at 35 to 40 degrees to the right. They are able to move their eyes but cannot fixate on specific visual stimuli (optic apraxia). patients field of attention is limited to one object at a time. making activities like reading difficult because each letter is perceived separately (simultanagnosia).
Rachman has also tested the effectiveness of this method in treating claustrophobia and found it to decrease fear and negative thoughts/connotations by an average of nearly 75% in his patients. Of the methods he tested in this particular study, this was by far the most significant reduction. Interoceptive exposure
This method attempts to recreate internal physical sensations within a patient in a controlled environment and is a less intense version of in vivo exposure. This was the final method of treatment tested by S.J. Rachman in his 1992 study. It lowered fear and negative thoughts/connotations by about 25%. These numbers did not quite match those of in vivo exposure or cognitive therapy, but still resulted in significant reductions.Other forms of treatment that have also been shown to be reasonably effective are psychoeducation, counter-conditioning, regressive hypnotherapy and breathing re-training. Medications often prescribed to help treat claustrophobia include antidepressants and beta blockers, which help to relieve the heart-pounding symptoms often associated with anxiety attacks. See also
