  Purpose
  • To determine the total and local gray matter volumes, and N-acetyl aspartate (NAA) levels in patients with bipolar disorders who are within euthimic, depressive or manic/hypomanic period and who are not taking drug;
  • To investigate the neuroprotective effects of long-term (6 weeks) use of valproate on total and local gray matter volumes and NAA levels.
  • To measure the brain electrical response to visual and auditory impulses before and after valproate treatment in patients within euthimic, depressive or manic/hypomanic period and who are not taking drug, and to compare the data with each other and with normal groups.
  • To determine the cognitive functions before and after the valproate treatment in the same patient group, to compare the data with each other and with age- and sex-paired normal controls;
  • To determine the relationship between these effects of valproate and clinical improvement;
  • To investigate the relationship between cognitive ability status and electrical activity of brain, to compare this with that in control group; to determine the relationship between the data and brain imaging (MRI/MRS) findings in conjunction with localization

Primary Outcome Measures:
  • To assess regional N-acetyl aspartate (NAA) levels in drug free bipolar patients either in manic/hypomanic, or depressive or euthymic state [ Time Frame: for 6 weeks ] [ Designated as safety issue: No ]
  • To investigate valporate's effect on total and regional gray matter volume and NAA levels; [ Time Frame: for 6 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To assess evoked and event related potentials to visual and auditory stimuli in patients before and after valproate monotherapy in comparison to healthy controls [ Time Frame: for 6 weeks ] [ Designated as safety issue: No ]
  • To determine the relationship between clinical improvement and image data changes in depressed or manic/hypomanic patients, [ Time Frame: for 6 weeks ] [ Designated as safety issue: No ]
