4. Results-
4.1 Socio-demographic data- Three groups were matched in terms
of gender, marital status, religion, residence but there is significant
difference in education (p=0.011) and occupation (0.000) (Table no 3).
Mean age of patients’ group with cannabis dependence was 30.57±12.90,
and there was no significant difference with groups of FDR and HC (Table
no 2).
4.2 Cognitive functions- Performance of attention task (digit
forward and digit backward) was significantly varied across three groups
(p<0.05 for both the test). Post-hoc test revealed performance
of digit forward in patients with cannabis use was significantly
impaired from normal healthy control group, though there was no
significant difference between group of FDR and HC. In digit backward
test, performance of patients with cannabis use was significantly lower
from normal healthy control. Performance of FDR group was reduced from
HC group but no significant difference between performance of patients
and FDR group (Table no 4).
In verbal memory test especially phonemic test, performance of patients
with cannabis use was impaired than FDR group, whose performance in turn
impaired from HC group. Though in categorical verbal memory, patients
with cannabis use performed worse than FDR and HC group, but no
significant difference was found between later two groups (Table no 4).
In our study visual memory was not differed significantly across three
groups (Table no 4).
In tests for executive functioning, performance of patients with
cannabis dependence was impaired compared to normal control as well as
their FDR. Significant difference (p<.05) was found in
mistakes of Stroop test and time for Trail-A test. But there was no
significant difference between FDR and HC group
(Table no 4).
