Despite the undoubted contribution of these investigations, the behavioral studies do not provide access to the understanding of the mechanisms underlying the observed functional outcome improvement.
The studies did not evaluate behavioral effects either; previous research has found that babies suffer withdrawal effects if they have been exposed to antidepressants in the womb, and that may have implications for later behavior.
The number of carriers in the available studies was relatively small and most studies did not systematically compare behavioral symptoms in mutation carriers with noncarriers, thus limiting the conclusions on whether there are distinguishing features specific to the mutation.
However, these studies did not provide information about a correlation of T. gondii infection with mental and behavioral disorders due to psychoactive substance use.
While three studies did not observe significant differences with regard to overall fear and anxiety [ 23], self-esteem [ 18] or overall behavioral difficulties [ 34], one study found significantly more behavioral difficulties in a sample consisting predominantly of adolescents [ 35].
Furthermore, short excerpts and discrete categories employed in many behavioral and neuroimaging studies do not capture dynamic aspects of musical emotion that unfold over larger time scales [24] [26].
These behavioral studies do, however, not provide access to the understanding of the mechanisms underlying the observed functional outcome improvement.
This may be because many implementation studies do not consider communication, behavioral, and health promotion theories in their design.
Although this study did not assess behavioral factors, such behavioral factors as activity levels as well as attitudes need to be considered, even in rural settings, to address all facets of malnutrition.
Most studies do not target diabetes specifically, however, and most do not rigorously address behavioral modifications.
