Evidence supporting the application of Brown's (1991, 1993) conception of behavioural addiction to computing behaviour is presented. Questionnaire items tapping Brown's addiction criteria were factor-analysed along with others, including computer apathy-engagement and computer anxiety-comfort items of Charlton and Birkett (1995). Items relating to some of Brown's criteria (tolerance, euphoria, and cognitive salience) were found to be complex, an Addiction factor loading upon them but an Engagement factor loading more highly. Items tapping other criteria (conflict, withdrawal, behavioural salience, and relapse and reinstatement) were shown to be factor pure, with only the addiction factor loading highly upon them. It is concluded that Brown's conception of behavioural addiction can be applied to computer-related behaviour, although the relationship of milder facets of addiction, which are also merely indicative of high engagement, to computer-related addictions is non-unique. It is also concluded that classifying individuals as exhibiting pathological computer use using checklists based upon adaptations of DSM criteria for pathological gambling is likely to overestimate the number of people addicted to computing activities.

A 31-year-old man with medication-refractory seizures in the context of right mesial temporal lobe sclerosis and right occipital encephalomalacia is described. He experienced the onset of obsessive-compulsive symptoms following resection of the right hippocampus and right occipital pole. Semistructured psychiatric evaluation was conducted 16 months after surgery. Results indicated that he fulfilled diagnostic criteria for obsessive-compulsive disorder (OCD) and that he was not depressed at the time of the evaluation. Total score on the Yale-Brown Obsessive Compulsive Scale was 24, indicating moderate symptom severity, and he had prominent symptoms related to contamination, washing, checking, repeating rituals, and ordering. He also reported significant problems with "not just right" experiences. Treatment with sertraline resulted in apathy. To our knowledge, the present case is only the fourth reported of de novo onset OCD following neurosurgery for seizure disorder, and the first in a patient without either preexisting obsessive traits or an OCD spectrum disorder.

Brown rice contains many ingredients that might protect against cognitive decline and Alzheimer's disease. However, brown rice is very hard, difficult to cook, and is poorly digested; thus, it is difficult to eat long-term. To solve these problems, ultra-high hydrostatic pressurizing brown rice (UHHPBR) was prepared. We investigated the effects of dietary UHHPBR administration for 24 mo on cognitive function and mental health in the elderly. Healthy elderly participants (n=52) were randomized into UHHPBR and polished white rice (WR) groups. The UHHPBR group consumed 100 g of UHHPBR per day for 24 mo and the WR group consumed white rice. At baseline, and after 12 and 24 mo, cognitive functions were assessed using the Revised Hasegawa's Dementia Scale, Mini-Mental State Examination, Frontal Assessment Battery (FAB), and the Cognitive Assessment for Dementia, iPad version (CADi). Mental health condition was also assessed using the Apathy Scale and the Zung Self-Rating Depression Scale, and serum biochemical parameters were determined. From baseline to month 24, the mean change in the FAB-sub item 1 scores was higher in the UHHPBR group compared to the WR group. Furthermore, apathy scores decreased, as well as the time required to answer all questions of the CADi, and plasma epinephrine levels increased. These results indicate that a 2-y oral consumption of UHHPBR increases information processing speed (as a measure of cognitive function) and improves apathy in the elderly, suggesting a protective effect of UHHPBR administration against age-related decline in brain cognition and motivation.
