Childhood hypersensitivity linked to OCD
Date:12/27/2011

In childhood, rituals like regular schedules for meal, bath, and bed times are a healthy part of behavioral development. But combined with oral and tactile sensitivities, such as discomfort at the dentist or irritation caused by specific fabrics, these rituals could be an early warning sign of adult Obsessive Compulsive Disorder (OCD).

According to Prof. Reuven Dar of Tel Aviv University's Department of Psychology, hypersensitivity and excessive adherence to childhood rituals may foreshadow the onset of OCD as the child ages. He first suspected the link while working with OCD patients who reported sensitivity to touch and taste as children. Now, in the first comprehensive study of its kind, Prof. Dar and his fellow researchers have established a direct correlation between sensory processing the way the nervous system manages incoming sensory information and ritualistic and obsessive-compulsive behaviors.

The study, which appears in the Journal of Behavior Therapy and Experimental Psychiatry, suggests that when children experience heightened levels of sensitivity, they develop ritualistic behaviors to better cope with their environment. In the long term, this is one potential pathway to OCD.

Connecting the behavioral dots

Two studies were devised to map the connection between sensory processing, rituals, and OCD. In the first, parents of kindergarten children were asked to complete three questionnaires on their child's behaviour their level of ritualism, such as the need to repeat certain acts or to order objects in a particular way; their level of anxiety, with questions relating to reaction to strangers, worrying about outcomes of events, and attachment to family members; and last, their reactions to everyday sensory events such as being touched or exposed to unusual tastes or smells.

In the second study, the researchers asked 314 adult participants to answer surveys online in relation to their
