We describe a 57-year-old man (MW) with frontal variant frontotemporal dementia (fv-FTD) who presented with a long history of drinking problem and marital disharmony followed by gradual changes in personality with disinhibition, stereotypic checking, overeating and a decline in self-care. Structural MRI imaging confirmed marked frontal atrophy involving particularly the ventromedial region. Performance on standard tests of frontal executive function was largely unremarkable and MW obtained a perfect score on the Mini-Mental State Examination (MMSE). In contrast, an experimental battery of tasks designed to evaluate theory of mind (ToM) revealed marked deficits. MW's challenging and disruptive behaviours, notably obsessive checking of car suspension by rocking, and wandering, responded to behavioural modification regimes adapted from the neurorehabilitation literature. In conclusion, deficits in ToM may underline the gross abnormalities in social conduct, which characterise fv-FTD; ToM appears to dissociate from frontal executive function; and behavioural modification approaches can be of benefit in this disorder.

Interventional studies, with the aim of reducing the burden of care through drug or non-drug therapies of behavioral and psychological symptoms of dementia (BPSD), have been scarce. However, we are now able to do pharmacological management for BPSD with new drugs such as atypical neuroleptics, SSRIs, and cholinesterase inhibitors. Delusions of theft are one of the most frequently observed BPSD in patients with AD. In addition, the delusions and ensuing aggression and anxiety are major factors that increase the burden of caregivers. Delusions of theft in patients with AD were eliminated or reduced with low-dose atypical neuroleptics (risperidone). This significantly reduced the burden of care overall for caregivers. New therapeutic strategies such as cholinesterase inhibitors for visual hallucinations in DLB and SSRIs for overeating and stereotyped behavior in FTLD might also remarkably reduce the burden of care for these patients. For many dementia patients, there are still no drugs that offer a principal cure. It is, therefore, important to evaluate their BPSD correctly at the earliest possible time, so that the burden of caring can be reduced through appropriate drug treatment. This reduction is critical for the continuation of satisfactory at-home care and might contribute to the health economics.

Frontotemporal dementia is a disorder of paralimbic prefrontal-insular circuitry. The disorder is often sporadic but can be caused by genetic mutations in tau, progranulin, valosin, TDP-43 and CHMP2b. The major clinical manifestations of FTD include addictive behaviors, disinhibition, apathy, overeating and loss of sympathy and empathy for others. Treatment is currently focused around symptoms but disease-modifying therapies seem feasible.
