[Frontotemporal dementia: neurotransmitter and clinical symptoms with focus on therapeutic targets].

Frontotemporal dementia is more frequently diagnosed because of revised diagnostic procedures. Due to the lack of pharmacological trials it is a disease that is difficult to manage in the way of evidence based medicine. Deficits in serotonergic and dopaminergic signal-transmission are well known. The cholinergic system does not seem to be affected. Case reports and clinical trials show a benefit by using antidepressants, neuroleptics and mood stabilizers. Nevertheless only paroxetine, trazodone and rivastigmine are tested by double-blind, placebo-controlled studies. While paroxetine shows inconsistent data, trazodone improves behavioural symptoms. Patients report a treatment-emergent adverse effect including fatigue, dizziness and hypotension. Rivastigmine leads to a significant decrease in the Neuropsychiatric Inventory Score. Finally, we present a two-cases-report that shows improve of disease symptoms under treatment with repetitive transcranial magnet stimulation.
