The prediction of the executive function of planning based on chronic stress, sensory processing sensitivity in patients with multiple sclerosis

The aim of this study is The  prediction of  executive function of planning based on  chronic stress, sensory processing sensitivity in patients with multiple sclerosis.

A sample of 100 patients with multiple sclerosis  of  Iran,s MS Society selected by available sampling and completed  two scales, chronic stress scale, sensory processing sensitivity and neuropsychological testing of Tower of London. Data were analyzed by SPSS software version 17.

the stepwise multiple regression analysis showed that among subscales of sensory process sensitivity, only low sensory threshold can predict function and time of planning. Whereas low sensory threshold predict 27 % variance of function of planning(p<0/001)and through entering of chronic stressto into the model sensory threshold and chronic stress predicted 0/37% variance of function of planning simultaneously(p<0/001). Also low sensory threshold predicted 27 % variance
Of tim of planning(p<0/005) and through entering of chronic stressto into the model increased to 33 %.

In order to explain the findings of this study it can be concluded that chronic stress lead to release stress hormone, that damage hypocamp and frontal lobe. Those both supress unrelated informations and establish planning and problem solving strategies. And low sensore threshold  eliminates and deters stimuluses and lead to  information processing disorder and planning impairement.
