The authors report on a patient with Parkinson disease (PD) and severe obsessive-compulsive disorder (OCD), in whom bilateral stimulation of the subthalamic nucleus (STN) was used to treat both PD and OCD symptoms. This 49-year-old man had displayed symptoms of PD for 13 years. Progressively, his motor disability became severe despite optimal medical treatment. In parallel, he suffered severe OCD for 16 years, with obsessions of accumulation and compulsions of gathering and rubbing that lasted more than 8 hours per day. Bilateral high-frequency STN stimulation was performed to treat motor disability. After surgery (at 1-year follow up), motor and OCD symptoms were dramatically improved. The pre- and postoperative Yale-Brown Obsessive-Compulsive Scale scores were 32 and 1, respectively. No additional antiparkinsonian drugs were administered. This case and other recent reports indicate that OCD symptoms can be improved by deep brain stimulation, a finding that opens new perspectives in the surgical treatment of severe and medically intractable OCD.
We considered the expression "nontraumatic epidural hematoma" to be less ambiguous than "spontaneous spinal epidural hematoma," which is the one that is usually used in the literature and corresponds to various definitions. In the absence of any signs suggestive of vascular malformation on magnetic resonance imaging, preoperative angiography is not essential and need not delay the surgical procedure, because the timing of the surgery, together with the preoperative clinical state, determines the quality of the clinical result.
Cerebral aneurysms and arteropathies causing severe cerebrovascular events have been reported as rare complications in patients with late-onset Pompe disease. We investigated the frequency of cerebrovascular anomalies in six patients with late-onset Pompe disease followed at our institution. Clinical data collection and magnetic resonance angiography were performed as part of routine annual examinations. Four out of six patients had brain vascular anomalies including dolichoectasia of the basilar artery and ectasia of internal carotids. These patients also complained of gastrointestinal symptoms (chronic constipation and gastrointestinal reflux). Two patients had clinical signs related to the arteriopathy, including partial paralysis of the third cranial nerve and transient ischemic attacks. At 1 year follow-up, enzyme replacement therapy did not modify the size of cerebral vessels, but patients reported a marked improvement of intestinal symptoms. In conclusion, neurologists should be aware that intracranial artery abnormalities are not infrequent in patients with late-onset Pompe disease, and they should be specifically investigated in the presence of unexplained CNS symptoms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
