Primary cervical dystonia is typically an adult onset condition with symptom onset usually in the fifth and sixth decade. Young onset (<28 years) is uncommon. We report 76 patients with cervical dystonia as a presenting or predominant feature, with disease onset before the age of 28. Male to female ratio was 1.24:1 and the mean onset age was 21 (3-28) years. A family history of tremor and/or dystonia was noted in 26.3%. Depression and anxiety attacks were present in 23.7%. Prior injury or surgery involving the neck was noted in 17.1%. 23 (30.3%) experienced spontaneous partial or complete remissions within the first 5 years of onset, but all relapsed. Cervical dystonia was predominantly rotational torticollis. 30% developed extra-nuchal dystonia and tremor affecting contiguous parts but in only one there was spread to affect the legs. All 15 patients tested for the DYT1 gene were negative. 74% responded favorably to botulinum toxin injections, whereas none of the 13 patients treated with L-Dopa preparations had a beneficial response. The distinctive features of this entity are discussed.

In-depth clinical psychological investigation of airline pilots with neurocirculatory dystonia (n=194, mean age 38.57 +/- 0.85) and essentially healthy control pilots (n=183, mean age 38.4+/-0.92) revealed distinctive features in NCD pilots' mentality and behavior including personality, interpersonal communication, type of thinking, stress reaction, protection tactics, and mental dysfunctions. Psychic deadaptation such as symptoms of psychic asthenia, paranoia, depression, schizophrenia, and impulsive behavior had a negative effect on the clinical course and led to medical disqualification of 15% of NCD pilots.

Deep brain stimulation (DBS) now plays an important role in the treatment of Parkinson's disease, tremor, and dystonia. DBS may also have a role in the treatment of other disorders such as obsessive-compulsive disorder, Tourette's syndrome, and depression. The neuropsychologist plays a crucial role in patient selection, follow-up, and management of intra-operative and post-operative effects (Pillon, 2002; Saint-Cyr & Trepanier, 2000). There is now emerging evidence that DBS can induce mood, cognitive, and behavioral changes. These changes can have dramatic effects on patient outcome. There have been methodological problems with many of the studies of DBS on mood, cognition, and behavior. The neuropsychologist needs to be aware of these issues when following up patients, and constructing future studies. Additionally, this article will review all aspects of the DBS procedure that can result in mood, cognitive, and behavioral effects and what role(s) the neuropsychologist should play in screening and follow-up.

Ropinirole is a non-ergoline selective D2 dopamine agonist. Its efficacy and safety has been established in several controlled double-blind studies in patients with early and advanced Parkinson's disease. It is assumed that the improvement in the activities of daily living under ropinirole is not only due to the improved motor symptoms but also due to the improvement of non-motor symptoms like symptoms of mood and anxiety. The objective of this post marketing surveillance study was to show that under the conditions of the daily routine in the neurologic practice ropinirole may not only improve motor symptoms, the activity of daily living and complications of the treatment (dystonia, dyskinesia) but also alleviate symptoms of depression and anxiety. A total of 110 neurological practices enrolled 327 patients in early and advanced stages of the disease (139 females, 188-males; mean age: 67 years). They were treated with ropinirole as monotherapy and as adjunctive therapy with l-dopa over a period of 12 - 14 weeks. Selected symptoms of the Unified Parkinson's Disease Rating Scale (UPDRS) part II-IV and symptoms of depression and anxiety were rated by the clinicians. Mood and functional impairment in job, family and social life were rated by the patients using selected items of the Beck Depression Inventory and the Sheehan Disability Scale (SDS). The different subtypes, i. e. the akinetic-rigid, tremor-dominant and the mixed subtype, are described separately. The total UPDRS score at baseline was similar for all three subtypes and there was also a similar improvement in the three groups under ropinirole. Both according to self-rating and to clinician rating the symptoms of depression and anxiety at baseline were more severe in the akinetic-rigid and the mixed subtype compared to the tremor-dominant subtype. The symptoms considerably improved and were reduced by 48 % under therapy with ropinirole. Adverse events were reported by 7.7 % of the patients. The surveillance study has shown that ropinirole may improve not only motor symptoms, activities of daily living and complications of treatment but also symptoms of mood and anxiety.

Blepharospasm (BSP) is a focal dystonia that results in hyperactivity of orbicular muscles of eyes. These symptoms often result in decreased quality of life (QoL) and symptoms of depression. Botulinum toxin type A is the current first line therapy. The aim of the present study was to analyze the impact of botulinum toxin treatment on the QoL and depressive symptoms in patients with BSP. The QoL was evaluated by means of the Short Form 36 questionnaire. The degree of the intensity of depression was evaluated by means of the Montgomery-Asberg Depression Rating Scale. Botulinum toxin treatment significantly improves the QoL and reduces the intensity of depressive symptoms in all our study patients with BSP.

The aim was to investigate differences by sex and music expertise in performance of a manual proprioceptive skill. Active left hand finger-movement discrimination for differences in string height was examined in a position similar to cello playing. Men and women who were experienced cellists and nonmusicians made active string depression movements and then made absolute judgments regarding which of five string positions were presented. Although no main effect was significant, analysis yielded a sex x musicianship crossover interaction (F(1,51) = 8.4, p = .006) wherein the female cellists performed better than the female nonmusicians, and the reverse occurred for males. These significant differences in active movement discrimination across sex and musicianship may be important in further understanding focal hand dystonia, a disorder wherein the interaction of sex and expertise is observed as a strong preponderance in experienced male musicians.

The use of deep brain stimulation (DBS) has recently been expanding for the treatment of many neurologic disorders such as Parkinson disease, dystonia, essential tremor, Tourette's syndrome, cluster headache, epilepsy, depression, and obsessive compulsive disorder. The target structures for DBS include specific segregated territories within limbic, associative, or motor regions of very small subnuclei. In this review, we summarize current clinical techniques for DBS, the cognitive/mood/motor outcomes, and the relevant neuroanatomy with respect to functional territories within specific brain targets. Future development of new techniques and technology that may include a more direct visualization of "motor" territories within target structures may prove useful for avoiding side effects that may result from stimulation of associative and limbic regions. Alternatively, newer procedures may choose and specifically target non-motor territories for chronic electrical stimulation.

The purpose of this study was to analyze the health-related quality of life (HRQL) of patients with cervical dystonia (CD) and the impact of botulinum toxin A (BTX-A) therapy in these patients. The authors recruited 101 patients with CD, all previously treated with BTX-A. Both before and 4 weeks after injection of BTX-A the patients were assessed using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS), a Visual Analogue Scale for pain (VAS: 0-100%), the Short Form 36 health survey questionnaire (SF-36), and the Montgomery-Asberg Depression Rating Scale (MADRS). A control group of 84 healthy volunteers was also evaluated. The patients? baseline SF-36 scores were worse in all the domains when compared with those of the controls. Depression was found in 47.5% of the patients. Improvements were noticed 4 weeks after the single BTX-A injections in all the SF-36 domains, and in the VAS, TWSTRS and MADRS scores. The TWSTRS results did not correlate with any of the SF-36 subscores. Stepwise backward regression analysis revealed depression as the main predictor of poor HRQL, as well as female sex, poor financial situation, and living alone. On contrary, longer treatment with BTX-A was associated with better scores. Cervical dystonia has a marked impact on HRQL and treatment with BTX-A injections has a beneficial effect, seen both in objective and in subjective measures. Depression in CD patients is a main predictor of worse HRQL.

The aim of this study was to assess health-related quality of life (HRQoL), using the Short Form Health Survey-36 (SF-36), in 70 cervical dystonia (CD) patients after long-term botulinum toxin (BTX) treatment (median 5.5 years), and to identify factors determining reduced HRQoL. We used combined patient-and physician-based measures to assess both CD severity [Toronto Western Spasmodic Torticollis Rating Scale, (TWSTRS)] and effect of long-term BTX treatment, and the Hospital Anxiety and Depression Scale (HAD) and General Health Questionnaire-30 to assess psychological distress. Mean SF-36 domain scores of the CD patients were reduced by <1 SD compared with age- and gender-matched population samples. High TWSTRS total scores and high HAD-depression (HAD-D) scores were the main factors associated with reduced scores in the physical and mental SF-36 domains, respectively. Patients evaluated to have a 'good effect' of long-term BTX treatment (n = 47), had significantly lower median TWSTRS total score, and a 3x lower frequency of high HAD-D scores, than those evaluated to an 'unsatisfactory effect' (n = 23). In conclusion, most CD patients enjoy a good HRQoL after long-term BTX therapy. Reduced HRQoL was associated with more severe disease and/or depressive symptoms.

Deep brain stimulation (DBS) has been approved by the FDA for use in the treatment of Parkinson's disease, essential tremor, and dystonia. Case reports and case series have reported significant psychiatric side effects in some individuals. The goal of this meta-analysis is to characterize the risks and benefits of DBS and to assess its possible use within the psychiatric setting. A search was conducted on PubMed, EBSCO, and PsycInfo in January 2006 that covered the time period 1 Jan 1996-30 Dec 2005. All identified articles were reviewed and those describing adverse events were further examined with a structured instrument. The initial searches yielded 2667 citations; 808 articles met inclusion criteria for the meta-analysis; 98.2% of studies that specifically assessed motor function reported some level of improvement. Most reported side effects were device or procedure related (e.g., infection and lead fracture). The prevalence of depression was 2-4%, mania 0.9-1.7%, emotional changes 0.1-0.2%, and the prevalence of suicidal ideation/suicide attempt was 0.3-0.7%. The completed suicide rate was 0.16-0.32%. In conclusion, DBS is an effective treatment for Parkinson's disease, dystonia, and essential tremor, and case reports suggest that major depression and OCD may also respond to DBS. Reported rates of depression, cognitive impairment, mania, and behavior change are low, but there is a high rate of suicide in patients treated with DBS, particularly with thalamic and GPi stimulation. Because of the high suicide rate, patients should be prescreened for suicide risk prior to DBS surgery. Additionally, patients should be monitored closely for suicidal behavior post-operatively.
