Deep brain stimulation of the nucleus accumbens and bed nucleus of stria terminalis for obsessive-compulsive disorder: a case series.

BACKGROUND Obsessive-compulsive disorder (OCD) is a psychiatric condition defined by the presence of obsessions, compulsions, or both. It has a lifetime prevalence of 2%-3% and causes significant impairment in social and work functioning, as well as a reduced quality of life. Treatment includes pharmacotherapy and psychotherapy, but a significant number of patients fail to respond to treatment. Deep brain stimulation has shown to be a safe and effective procedure for severe, chronic, treatment-resistant OCD, and several surgical targets have been proposed for treatment, including the nucleus accumbens, the anterior limb of the internal capsule, the subthalamic nucleus, the globus pallidus, and the bed nucleus of stria terminalis. OBJECTIVES To report the first Italian case series of patients who underwent DBS of 2 distinct targets for OCD: nulceus accumbens and bed nulceus of stria terminalis. METHODS Four patients underwent DBS of the nulceus accumbens, and 4 patients underwent DBS of the bed nucleus of stria terminalis. RESULTS Six patients showed a significant improvement in OCD symptoms. CONCLUSIONS DBS of these 2 structures is a safe and effective procedure for the treatment of severe, refractory OCD.

Capgras delusion for animals and inanimate objects in Parkinson’s Disease: a case report

BackgroundCapgras delusion is a delusional misidentification syndrome, in which the patient is convinced that someone that is well known to them, usually a close relative, has been replaced by an impostor or double. Although it has been frequently described in psychotic syndromes, including paranoid schizophrenia, over a third of the documented cases of Capgras delusion are observed in patients with organic brain lesions or neurodegenerative disease, including Parkinson’s Disease. Variants of Capgras involving animals or inanimate objects have also been described. The etiology of Capgras in Parkinson’s remains unclear, but may arise from a combination of factors, such as frontal lobe dysfunction and dopaminergic medication.Case presentationWe present the case of a 53-year old right-handed female with Parkinson’s disease who developed Capgras delusion during treatment with dopamine agonists and Levodopa/Carbidopa. She became convinced that her pet dogs and the plants in her garden had been substituted by identically looking ones. Our patient was initially treated with Quetiapine, with no improvement, and subsequently treated with Clozapine, which lead to partial regression of her symptoms. Neuropsychological Evaluation showed Mild Cognitive Impairment in Executive Functions.ConclusionsGiven the clinical history, onset and evolution of symptoms we believe our patient’s delusion resulted from the overlap of dopaminergic medication and Mild Cognitive Impairment in executive functions. Zoocentric Capgras, the variant we describe, has been rarely described in scientific literature, and we believe it is of interest due to its unusual characteristics.

First- and Third-Person Perspectives in Psychotic Disorders and Mood Disorders with Psychotic Features

Lack of insight, very frequent in schizophrenia, can be considered a deficit in Theory of Mind (ToM) performances, and is also found in other psychiatric disorders. In this study, we used the first- to third-person shift to examine subjects with psychotic and psychotic mood disorders. 92 patients were evaluated with SANS and SAPS scales and asked to talk about their delusions. They were asked to state whether they thought what they said was believable for them and for the interviewer. Two weeks later, 79 patients listened to a tape where their delusion was reenacted by two actors and were asked the same two questions. Some patients gained insight when using third-person perspective. These patients had lower SAPS scores, a lower score on SAPS item on delusions, and significant improvement in their SAPS delusion score at the second interview. Better insight was not related to a specific diagnostic group.

Psychiatric issues in patients with headaches.

Comorbidities among headaches and psychiatric disorders have been consistently reported in several clinical studies and reviews. In this paper, we review some recent clinical studies on migraine and tension-type headaches associated with mood, anxiety and somatoform disorders, focusing on therapeutic strategies for the psychiatric disorders.

Obsessive-compulsive disorder presenting with musical obsessions in otosclerosis: a case report

IntroductionMusical obsessions consist of intrusive recollections of music fragments that are experienced as unwanted. Otosclerosis is caused by an abnormal bone homeostasis of the otic capsule and represents a frequent cause of hearing impairment. Many conditions causing hearing loss have been associated with musical hallucinations, but the association between musical obsessions and hearing loss is frequently overlooked.Case presentationWe present the case of a 51-year-old Caucasian woman with a history of obsessive-compulsive disorder who developed musical obsessions soon after being diagnosed with otosclerosis. She was referred to our obsessive-compulsive disorder outpatient unit by her general psychiatrist. At the time of our first evaluation, she had severe musical obsessions that interfered with her social functioning and made her unable to follow conversations. She was started on 40mg of paroxetine and 2.5mg of aripiprazole, which led to significant improvement of her symptoms and of her social and work functioning.ConclusionsTo the best of our knowledge, this is the first report of musical obsessions in a patient with hearing loss due to otosclerosis and a history of obsessive-compulsive disorder. This case suggests that a differential diagnosis of obsessive-compulsive disorder should be carefully considered in patients with hearing impairment who complain of involuntary musical imagery, especially in those patients who have a previous history of obsessive-compulsive disorder.

Neuropsychiatric Disturbances in Dystonia

A recent consensus update classifies dystonia according to two main axes describing the motor features and the different etiologies. Dystonia with no other neurological signs is called “isolated,” whereas dystonia associated with other neurological signs is called “combined.” Since its first description by Oppenheim, dystonia has been considered a pure motor disorder, but recently non-motor features have been recognized as part of clinical phenotype. In isolated dystonias psychiatric disturbances including depression, anxiety disorders, and obsessive-compulsive disorder have been frequently reported. Also cognitive deficits, mainly of executive and visuospatial domains, have been observed, but no major cognitive impairment or dementia was reported. In combined dystonias, psychiatric and cognitive dysfunctions are described, with differences among specific syndromes. The topic of neuropsychiatric features in dystonia is evolving and further studies are needed to elucidate the observed phenomenological diversities.

P01-27 - Depression and subclinical hypothyroidism

Objectives To estimate the prevalence of depressive symptoms in patients affected by subclinical hypothyroidism by means of Hamilton Rating Scale for Depression (HAM-D) and Montgomery-Asberg Depression Rating Scale (MADRS); to assess which depressive symptoms are prevalent in our population, with references to the factorialization of HAM-D by Cleary and Guy (1977); to verify whether levothyroxine replacement therapy alone can induce total remission of depressive symptoms. Methods The study enrolled 63 patients affected by subclinical hypothyroidism undergoing follow-up at the endocrinology service of San Paolo Hospital in Milan. All patients underwent an evaluation by means of HAM-D and MADRS scales and serum TSH, free T4, free T3, TPO-Ab and Tg-Ab levels were measured. Results We estimated a prevalence of depressive symptoms in our population of 63.5%. Concerning the qualitative assessment of psychiatric disturbances in the population we considered, our results showed that the most frequent symptoms were part of four factors, according to the Cleary and Guy factorialization of HAM-D: these factors are representative of anxiety and somatisation (factor I), cognitive impairment disturbances (factor III), psychomotor retardation (factor V) and sleep disorders (factor VI). Levothyroxine replacement therapy alone wasn’t effective in inducing total remission of depressive symptoms. Conclusions This study suggests the importance of a psychiatric evaluation in patients affected by subclinical hypothyroidism.

P03-67 - Insight and delusions in psychotic disorders and mood disorders with psychotic features

Objectives Our goals were to evaluate if the presence of severe delusions negatively affects insight, regardless of diagnosis, and whether or not patients gain insight into their delusions when using a third person perspective. Methods 92 delusional patients with psychotic and psychotic mood disorders were asked to speak about their delusions and were evaluated by means of the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms (SAPS and SANS). They were then asked to state whether they thought what they said was believable for them and for the interviewer. After two weeks 79 patients were evaluated with the same scales and listened to a tape where their delusion was re-enacted. They were then asked to state if what they heard was believable for them and for the interviewer. Results 12 patients thought their delusions was unbelievable for the interviewer at first interview, and 17 patients did the same after the second interview; 4 patients stated what they heard from the tape after the second interview was unbelievable both for them and interviewer. Patients with better insight (patients who stated their delusion was not believable) had a lower SAPS score, a lower item delusion score and a significant improvement of item delusion score at second interview Conclusion Several patients gain partial insight when using a third person perspective. The severity of delusions negatively affects insight, regardless of the patients diagnosis.
