Methods Design Analysis of data derived from two separate data banks. Sample 54 subjects 32 with HT 29 women mean age 22 without HT 19 women mean age . Assessment Psychiatric diagnosis was carried out by Simplified Composite International Diagnostic Interview CIDIS using DSM-IV categories cerebral perfusion was measured by 99 mTc-ECD SPECT. Statistical analysis was done through logistic regression. Results MDD appears to be associated with left frontal hypoperfusion left temporal hypoperfusion diffuse hypoperfusion and parietal perfusion asymmetry. A statistically significant association between parietal perfusion asymmetry and MDD was found only in the HT group. Conclusion In HT MDD is characterized by a parietal flow asymmetry. However the specificity of rCBF in MDD with HT should be confirmed in a control sample with consideration for other health conditions. Moreover this should be investigated with a longitudinally designed study in order to determine a possible pathogenic cause. Future studies with a much larger sample size should clarify whether a particular perfusion pattern is associated .
