 s symp Recent research  Zakzanis; conclusion tha the specific role of deficits in the temporal lobes has been overstated and that more diffuse dysfunction exists  MRI studies found a subtle 4% but significant bilateral hippocampal volume reduction in ppl with s  Regional volume reductions were esp marked in bilateral medial temporal lobe regions  Reported finding reduced hippocampus volume amog twins with s relative to twins without s  They reported that ppl had smaller medial temporal lobe volumes relative to controls but that the volume diff was not specific for either region or hemisphere  Reduced cerebral blood volume accompanies brain size in s and proposed that chronic cerebral blood volume eventually results in neuronal loss and cognitive impairments  The results suggested that violet ppl with s and a history of anti social and or substance use manifest neural dysfunction affecting basal or orbital pats or the prefrontal cortex Psychological stress and s  Data as show that as with other dis increased in life stress increase the likelihood of a relapse  Ppl who take pare in stress mgt program are less likely to be readmitted to the hospital the year following treatment esp if they had attended treatment session regularly  Two stressed have played an imp role in s: social class and family Social class and s  S are found in central city areas inhibited by ppl in the lowest socio economic class nd  The rate of s was found to be twice as high in the lowest social cllowest classe 2  Found tat ppl with s are downwardly mobile in occupational status.

This blamed the mom for child’s psychiatric disorder. Mother theory had not yielded supporting data  A family communication pattern characterized by hostility and poor communication produced the later onset of s or s related disorders  10% of the ppl returning to the low EE homes has relapse .in marked contrast in the same period 58% of the ppl returning to high EE homes had hone back to the hospital  it has also been fond that negative symp of s are the more likely to elicit critical comments  EE mothers are highly sensitive to excitement and depression in the patient and report a high level of burden associated with their kids illness. These mothers also have a personality characterized by high levels of conscientiousness and lowest levels of neurotism  Research indicates that both interpretations of the operation of EE –the casual and the reactive may be correct.  Two key findings emerged: 1) the expression of unusual thoughts by the patients elicited higher levels of critical comments by family members who had previously been characterized as high in EE 2) in high EE families critical comments by family members led to increased expression of unusual thoughts  Thus the study found a bi-directional relationship: critical comments by members of high EE families elicited increased expression of unusual thoughts by patients and unusual thoughts expressed by patients led to i
