Abstract
Akathisia is one of the most vexing problems in neuropsychiatry. Although it is one of the most common side effects of antipsychotic medications, it is often difficult to describe by patients, and is difficult to diagnose and treat by practitioners. Akathisia is usually grouped with extrapyramidal movement disorders (ie, movement disorders that originate outside the pyramidal or corticospinal tracts and generally involve the basal ganglia). Yet, it can present as a purely subjective clinical complaint, without overt movement abnormalities. It has been subtyped into acute, subacute, chronic, tardive, withdrawal-related, and "pseudo" forms, although the distinction between many of these is unclear. It is therefore not surprising that akathisia is generally either underdiagnosed or misdiagnosed, which is a serious problem because it can lead to such adverse outcomes as poor adherence to medications, exacerbation of psychiatric symptoms, and, in some cases, aggression, violence, and suicide. In this article, we will attempt to address some of the confusion surrounding the condition, its relationship to other disorders, and differential diagnosis, as well as treatment alternatives.

Abstract
Child neglect can be difficult to recognize. Parental substance abuse may place a child at increased risk of neglect. This report reviews 2 cases of dystonic reaction in children after accidental exposure to cocaine in their home environments. The reports are followed by a review of proposed physiologic mechanisms for cocaine-induced dystonia and a discussion on neurological symptoms that may develop after cocaine exposure. Pediatric emergency physicians should consider cocaine exposure when a child of any age presents with abnormal movements. Dystonic reaction is an uncommon, but reported, complication of cocaine exposure in the absence of other risk factors and may be the first presentation of child neglect.

Abstract
OBJECTIVE To provide an overview of some of the most common drug-induced movement disorders (DIMD) seen in the elderly by the primary care clinician. The epidemiology, clinical presentation, differential diagnosis, treatment, risk factors, and preventive measures are presented for each DIMD. DATA SOURCES Medical literature and research article search utilizing PubMed (National Library of Medicine), Psych INFO (American Psychological Association), CINAHL Database (CINAHL Information Systems), the Library of Congress Catalogue, and the Internet. STUDY SELECTION Reviews and articles from 1954 to 2005 concerning various movement disorders associated with medication in older adults. DATA EXTRACTIONS: Data on movement disorders associated with medications ranging from possible or controversial to well-established. DATA SYNTHESIS With the aging of populations in the United States and other countries, the use of medications with potential risk of precipitating movement disorders is increasing. The majority of these iatrogenic problems will be first seen in the geriatric patient in various clinical settings, typically in a primary care setting. To a large extent they will be observed in patients with mild cognitive impairment or dementia having impaired recall and reduced capacity to participate in the diagnostic interview. The challenge to clinicians is complicated by the sizable number of medications that may be involved.

Abstract
BACKGROUND Medication side-effects such as tardive dyskinesia (TD) are known to occur in individuals with a history of psychotropic drug use. This study aimed to contribute to the development of measures for assessing TD by examining the validity of the Matson Evaluation of Drug Side-effects (MEDS) with the Dyskinesia Identification System: Condensed User Scale (DISCUS) in 163 adults with intellectual disability (ID). METHOD To establish convergent validity, the relationship between the MEDS and the DISCUS in identifying TD was examined. To establish divergent validity, the ability of the MEDS to differentiate between TD and other side-effects was investigated. RESULTS The MEDS demonstrated convergent validity with the DISCUS on the Central Nervous System--Parkinsonism/Dyskinesia (CNS-PD) Subscale. The MEDS showed divergent validity with the DISCUS in cardiovascular and gastrointestinal side-effects, Parkinsonism symptoms (i.e., tremor, mask-like face), dystonia, and akathisia. DISCUSSION The MEDS appears to have significant clinical utility in measuring tardive dyskinesia and other medication side-effects in individuals with ID.

An assessment of emergent tardive dyskinesia and existing dyskinesia in patients receiving long-acting, injectable risperidone: results from a long-term study. Schizophr Res 2005; 77:129-39. [PMID: 15913962 DOI: 10.1016/j.schres.2005.03.015] [Citation(s) in RCA: 30] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2004] [Revised: 03/15/2005] [Accepted: 03/17/2005] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Treatment-emergent tardive dyskinesia (TD) can be a serious side effect of antipsychotic treatment. Atypical antipsychotics are associated with a lower risk for TD than are conventional agents. A long-acting atypical antipsychotic, with more stable blood levels and lower peak blood levels than an oral formulation, may provide differential benefit regarding side effects, including movement disorders. This analysis assessed TD by defined research criteria in patients receiving long-acting, injectable risperidone. METHODS Clinically stable subjects with schizophrenia or schizoaffective disorder participated in a 50-week, open-label trial of long-acting, injectable risperidone. TD was studied by defined research criteria (Schooler, N.R., Kane, J.M., 1982. Research diagnosis for tardive dyskinesia. Arch. Gen. Psychiatry. 39, 486-487; Americal Psychiatric Association, 2000. Diagnostic and Statistical Manual of Mental Disorders, fourth ed. American Psychiatric Association, Washington, DC). The severity of dyskinesia and other movement disorders were rated by the Extrapyramidal Symptom Rating Scale (ESRS). RESULTS ESRS dyskinesia data were available for 662 patients. Five of 530 subjects without dyskinesia at baseline (0.94%) met the predefined criteria for emergent persistent TD during therapy. Based on either exposure to study medication or Kaplan-Meier analysis, the 1-year rate was 1.19%. Among the 132 subjects with dyskinesia at baseline, the mean score on the ESRS physician's exam for dyskinesia improved significantly at endpoint (-2.77; P<0.0001), regardless of anticholinergic drug use. (P=0.243 for patients with versus without anticholinergic drug use.) CONCLUSIONS In this open-label study, treatment with long-acting risperidone was associated with a low rate of emergent persistent TD. Significant improvement in existing dyskinesias was noted. The TD rate reported here is consistent with other reports of atypical antipsychotics and substantially lower than with conventional antipsychotics.

Abstract
Agitation is a major problem for older people and is present in over half of the hospitalizations for people > 65 years of age. In a previous study by the authors, results indicated that nursing actions often did not meet best-practice standards in the care of older, agitated patients. This paper builds on these results by reviewing the literature pertaining to the use of restraints and contributes to the body of knowledge surrounding the impact of the acute-care experience on rehabilitation outcomes. Successful rehabilitation relies on the improvement of functional health outcomes and, for this to happen, physical and emotional well-being are important. The sequelae of restraint use in acute care have the potential to alter peoples' ability to participate fully in a rehabilitation programme, thereby placing their future placement at risk. This paper explores the outcomes of restraint use in the acute-care setting and presents the argument that their effects are likely to be detrimental to rehabilitation outcomes.

Abstract
Serotonin syndrome (SS) is a potentially fatal complication of the combined use of agents that enhance serotonin activity. Bupropion inhibits noradrenaline and dopamine reuptake with milder effects on serotonergic activity. Although regarded as a potential causative agent for SS, no cases have been reported in the medical literature. A 62-year-old woman treated with therapeutic dosages of bupropion and sertraline for depression for the previous 3 weeks presented with upper extremity myoclonic jerks, clumsiness, and gait difficulties with fluctuating symptoms of confusion, forgetfulness, and the alternation of agitation and lethargy. Symptoms were interpreted as an aggravation of depression and venlafaxine was added. The clinical picture progressed to alteration of consciousness and dysautonomia. After admission, medications were discontinued and she was started on cyproheptadine and clonazepam with gradual improvement and complete resolution of symptoms. This is a rare report of SS related to the association of bupropion and selective serotonin reuptake inhibitors (SSRIs). It also illustrates the potential for misinterpretation of the earliest manifestations of SS as signs of aggravation of the patient's underlying condition. The role of bupropion in SS is possibly related to its well-established specific inhibition of the cytochrome P450 2D6 pathway, increasing blood levels of SSRIs and tricyclic antidepressants.

Abstract
The main clinical characteristics and aetiology of drug-induced tremor and acute movement disorders (myoclonus, chorea, athetosis, dyskinesia, dystonia, tics) are reviewed and discussed in this article. Tremor is the most frequent drug-induced acute movement disorder. Drug intake (and, initially, true or 'hidden' neuroleptic or psychoactive drugs) should be suspected as the cause of every abnormal movement. Drug-induced acute movement disorders usually disappear spontaneously after withdrawal of the suspected drug without any drug treatment. Drug-induced tremor and movement disorders are often poorly described in the Summary of Products Characteristics (SPC).

Abstract
Juvenile parkinsonism (JP) is a clinically and etiologically heterogeneous entity. Unlike in the adult form, secondary causes, hereditary and metabolic conditions, are the predominant causes of JP. Idiopathic Parkinson's disease is very rare in this age group. In most cases of JP, parkinsonism is accompanied by other neurologic features, such as dystonia, cognitive impairment, seizures, oculomotor and visual dysfunction, and ataxia. Systemic findings, such as liver dysfunction or hepatosplenomegaly, may be present depending on the cause. This review article describes the clinical characteristics, classification, genetic basis, pathophysiology, biochemistry, pathology, and treatment of JP.
