102 The role of these drugs in the prevention

and treatment of ZD6474 concentration vascular depression can be examined in patients with ischemic events participating in acute intervention and secondary prevention trials. Treatment of vascular depression Psychotropic drugs used in depressed elderly patients may influence recovery from ischemic lesions. Animal studies suggest that the dopamine receptor blocker haloperidol, the α1-adrenergic receptor antagonists trazodone and amitriptyline, Inhibitors,research,lifescience,medical the ;2-adrenergic receptor clonidine, and GABA agonists such as diazepam and phenytoin interfere with motor recovery after ischemic lesions.102-104 In contrast, amphetamine, desipramine, the dopamine agonist bromocriptine, and the ;2-adrenergic receptor antagonists yohimbine and idazoxan may be beneficial to recovery from ischemic injury.102-104 A clinical study has observed that fluoxetine may facilitate and maprotiline may hinder recovery in poststroke hémiplégie patients undergoing rehabilitation.105

Inhibitors,research,lifescience,medical Studies may examine which psychotropic agents influence the incidence of poststroke depression or alter the course of vascular depression, and identify antidepressants suitable for prophylaxis of vascular Inhibitors,research,lifescience,medical depression. The presence of subcortical abnormalities and their adverse impact on the treatment response and the longterm outcome of vascular depression provide the rationale for studies of agents that influence the neurotransmitter systems of frontostriatal circuitry. Further Inhibitors,research,lifescience,medical research may determine the efficacy of drugs acting on the dopamine, acetylcholine, and opiate systems of prefrontal pathways in patients with vascular depression. We have observed a relationship between disability and abnormal scores of initiation/perseveration and psychomotor retardation,10 abnormalities that frequently occur in vascular depression. Disability is also associated with anxiety Inhibitors,research,lifescience,medical and depressive ideation in depressed

elderly patients.10 Cognitive behavioral therapy combined with rehabilitation approaches have been found to reduce depression and improve quality of life.106 Such interventions may be useful in disabled patients with vascular depression provided that they are individualized and address the cognitive deficits of these patients. Conclusion Clinical and neuroimaging no studies suggest that cerebrovascular disease may predispose, initiate, or perpetuate late -life depression, perhaps by compromising the integrity or regulation of CSPTC systems. The heuristic value of the vascular depression hypothesis is that it provides the background for studies of mechanisms of depression. Lesions at specific locations may promote, have no effect, or even protect patients from depression. The lesion burden concept may be relevant to some cases of vascular depression.
