Review Meta Analysis
Radiosurgery for the treatment of psychiatric disorders: a review.
Radiosurgery for psychiatric disorders has been performed for more than 50 years. The use of deep brain stimulation has recently been expanded to the investigational treatment of specific psychiatric disorders. ⋯ The anatomic target localization, dose selection, and the outcome of the radiosurgical procedures were reviewed, and the evolutions of lesioning strategies were analyzed with particular emphasis on the dose selection. Large-scale prospective studies with strict inclusion and well-defined, objective outcome criteria are necessary for defining the role of radiosurgery for the treatment of psychiatric disorders.

Deep brain stimulation (DBS) is a therapeutically effective neurosurgical method originally applied in movement disorders. Over time, the application of DBS has increasingly been considered as a therapeutic option for several neuropsychiatric disorders, including Gilles de la Tourette syndrome, obsessive compulsive disorder, major depression and addiction. Latest research suggests beneficial effects of DBS in Alzheimer dementia (AD). Because of the high prevalence and the considerable burden of the disease, we endeavored to discuss and reveal the challenges of DBS in AD. ⋯ Considering the large number of patients suffering from AD, there is a great need for novel and effective treatment methods. Our research provides insights into the theoretical background of DBS in AD. Providing that our hypothesis will be validated by our ongoing pilot study, DBS could be an opportunity in the treatment of AD.

To review the use of deep brain stimulation (DBS) for treatment of dementia. ⋯ Evidence for the use of DBS to treat dementia is preliminary and limited. Fornix and nucleus basalis of Meynert DBS can influence activity in the pathologic neural circuits that underlie AD and Parkinson disease dementia. Further investigation into the potential clinical effects of DBS for dementia is warranted.

Lesion procedures for psychiatric indications have a history that spans more than a century. This review provides a brief history of psychiatric surgery and addresses the most recent literature on lesion surgery for the treatment of anxiety and mood disorders. ⋯ Lesioning procedures have informed modern deep brain stimulation targets. Recent lesioning studies demonstrate the efficacy and durability of these procedures in severely disabled patients. Judicious application of these techniques should continue for appropriately selected patients with severe, refractory psychiatric disorders.
