The current role of neurosyphilis in the differential diagnosis of neuropsychiatric diseases

Over a period of eight years, 16 patients from a non-selected number of patients in a neuropsychiatric special hospital were diagnosed to suffer from neurolues not known so far. Apart from the classical clinical pictures (PP and T. d.) meningovascular courses of disease with apoplectiform onset have been dominant since 1980. The patients concerned were nearly exclusively younger male adolescents. The decline in the classical development of neurolues in favour of meningovascular and atypical clinical pictures makes clinical diagnosis more difficult and requires routine application of standardized specific and serological tests in clinical practice.     

Conclusions from shifts in morbidity patterns of hospitalized children with neuropsychiatric diseases

The decrease of neurological illnesses and the corresponding increase of psychogenic disturbances by patients belonging to clinical departments of neuropsychiatry of child and youth are described. This conversion leads to a frequently longer staying of the patients within the clinics. Furthermore, changes of the behaviours of the whole team for treatment may be observed.     

The unstable-frequency EEG--as a concept and its correlations to neuropsychiatric diseases in children

A total of 21,040 electroencephalograms obtained from 6,834 children constituting the routine patient stock of an electroencephalographic department of a pediatric clinic were checked for "frequency instability". It was possible to observe an age dependence of this characteristic and determine statistical correlations with certain clinical disease units showing different frequencies of this particular characteristic, especially neuropathies and neuroses.     

Neuropsychopharmacologic treatment of depression and other neuropsychiatric disorders in HIV-infected individuals

How can neuropsychiatric disorders and syndromes be underdiagnosed and inadequately treated in individuals infected with human immunodeficiency virus? Depression in particular is among the most prevalent diagnoses and there is a solid foundation of data from controlled clinical studies that has begun to examine the efficacy of various antidepressants in HIV-infected persons. This article summarizes essential findings pertaining to the use of psychotropic medications to treat depression and other neuropsychiatric disorders in the context of immunodeficiency. This includes discussion of clinically significant treatment considerations (eg, efficacy, side effects, drug-drug interactions) derived from the existing literature. Taken together, there is compelling evidence that psychopharmacologic intervention can improve the quality of life of mentally ill HIV-infected individuals.     

Role of norepinephrine in the pathophysiology of neuropsychiatric disorders

The concatenation of convergent lines of evidence from basic to clinical research continues to reveal that norepinephrine (NE) is a crucial regulator of a myriad of behaviors ranging from stress response to memory formation. Furthermore, many neuropsychiatric disorders involve neurocircuitry that is directly modulated by NE. This report summarizes the physiological roles of NE, as well as the main findings implicating a role for NE system dysfunction in mood and anxiety disorders, posttraumatic stress disorder, attention-deficit/hyperactivity disorder, and Alzheimer's disease. In each of these disorders, there appears to be a complex dysregulation of NE function, with changes in locus ceruleus firing, NE availability, and both pre- and postsynaptic receptor regulation. Many symptoms of these disorders are attributable to abnormalities within distributed neural circuits regulated by NE. Appreciation of NE's role in modulating the neural circuitry mediating cognition and affect should help elucidate the pathophysiology of a variety of neuropsychiatric disorders and the development of novel treatments.     

Cognitive behavioural and neuropsychiatric treatment of post-traumatic conversion disorder: a case study

Conversion disorder consists of involuntary sensory or motor symptoms and deficits that cannot be explained by a general medical condition. There are several treatment options, although none has emerged as the treatment of choice. The present case study examined the effects of adding cognitive behaviour therapy to neuropsychiatric management of conversion disorder (motor subtype). The patient, a retired emergency services worker, presented with a history of intermittent episodes of speech disruption (inability to speak or difficulty speaking properly). Although episodes of speech disturbance sometimes occurred unexpectedly, they were more likely to occur under conditions of stress and fatigue, and were triggered by reminders of work-related traumatic events. The patient was treated with pharmacotherapy and psychoeducation from a neuropsychiatrist. With the aim of improving treatment outcome, cognitive behaviour therapy was added, involving imaginal exposure to trauma memories, along with cognitive restructuring. The frequency of between- and within-session speech disturbance episodes declined over the course of cognitive behaviour therapy to the point that the patient was essentially symptom-free. Within-session distress ratings also decreased, which suggested habituation to trauma-related memories. This case study demonstrates how particular cognitive behaviour therapy interventions can be usefully applied to one form of conversion disorder.     

Recognition of facial emotions in neuropsychiatric disorders

Recognition of facial emotions represents an important aspect of interpersonal communication and is governed by select neural substrates. We present data on emotion recognition in healthy young adults utilizing a novel set of color photographs of evoked universal emotions. In addition, we review the recent literature on emotion recognition in psychiatric and neurologic disorders, and studies that compare different disorders.     

Forensic neuropsychiatric aspects of epilepsy

Epilepsy may be associated with automatisms that are classed as ‘insane ‘as they are deemed to have originated within the mind. ‘Sane automatism’ is said to occur from external factors, such as physical trauma, while ‘insane automatism’ is said to be innate to the individual experiencing them. To claim automatism within the context of a criminal matter requires a detailed evaluation of the behavior demonstrated and a questioning of the volitional and purposeful nature of this behavior. It is insufficient to rely upon past behavior in association with these seizures to justify the defense of automatism within a specific event. Epilepsy is often considered to be associated with an increase in violence. Proper epidemiological research, both in long-term, large population control studies and hospital-based studies, has suggested that epilepsy, per se, is not associated with an increase in violence when compared to the population at large and controlled for other familial and environmental factors.     

Biomagnetism from the neuropsychiatric viewpoint--principles of recent developments in diagnostic procedure

The following survey is intended to demonstrate and discuss some principle problems of biomagnetism and the application in clinical fields. The development of special technical parameters especially by the SQUID method is initiating new possibilities of research and completing the neurobiologically determinated basis and conditions of neuropsychiatric disorders. The Magnetoencephalography (MEG) will be represent an important role of a new functional diagnostic method.     

Traditional treatment procedures in neurologic-psychiatric diseases in Ethiopia

This is a report, based on a one year's stay at the hospital of the Gondar College of Medical Sciences (PDR Ethiopia), on the usage of traditional therapeutic practices as described by patients of the neurologic-psychiatric department in their histories. More frequently than others, psychotic patients, patients suffering from headache, and patients complaining of fits had used traditional treatments before seeking medical help.     

Enrolling decisionally incapacitated subjects in neuropsychiatric research

This paper discusses the National Bioethics Advisory Commission's (NBAC's) report on research involving persons with mental disorders that may affect decisionmaking capacity. After placing the NBAC recommendations into their historic context, the authors propose a strategy to enroll decisionally incapacitated subjects into neuropsychiatric research. The authors maintained that their proposed consensus model for research authorization, utilizing subject advocates, fosters valuable clinical research while protecting potentially vulnerable subjects.     

An overview of malingering and deception in neuropsychiatric cases

Forensic practitioners must shoulder special responsibilities when evaluating over-stated pathology (e.g., malingering) as well as simulated adjustment. Such determinations may modify or even override other clinical findings. As a result, practitioners must be alert to their own misassumptions that may unintentionally bias their conclusions about response styles. Detection strategies for malingering—based on unlikely or markedly amplified presentations—are highlighted in this article. Given page constraints, assessment methods for feigning are succinctly presented with their applications to administrative, civil, and criminal referrals.     

Concomitant neuropsychiatric symptoms in a case of Ehlers-Danlos syndrome

The case of a 15-year-old boy with Ehlers-Danlos-Syndrome (EDS) is described. Clinically the symptoms of considerable hyperextension of joints, abnormal extensibility of skin, moderate bleeding tendencies and slight vulnerability of the skin, deformity of the thorax are corresponding with type I of EDS. Ocular symptoms are missing. Histologically the picture is that of mitis type resp. type II of EDS. An autosomal dominant inheritance is to be supposed. Psychically an imbecillity likely as a result of perinatally acquired brain damage, and an autistic syndrome of broken home situation are present. Differential diagnosis and genetic significance of EDS are discussed.     

Some psychoanalytic viewpoints on neuropsychiatric disorders in children

The author addresses issues interfacing neuropsychiatry and psychoanalysis. He recommends psychoanalysis for children with Attention Deficit, Hyperactivity Disorder (ADHD) and Dysfunction in Attention and activity control, Motility control and Perception (DAMP). He attributes its low status in neuropsychiatric treatment recommendations partly to the fact that psychoanalysts do not always declare their specific field of investigation. The scientific community then assumes that psychoanalysis aims to comment on issues outside its field of investigation, e.g. on neurobiological aetiology. The community therefore fails to discern the psychoanalyst's specific task, to help the child express and work through his conscious and unconscious experiences. Clarity on the analyst's part will improve relations with the scientific community and facilitate a relevant comparison of treatment methods. Another reason for neuropsychiatry's negative attitude towards analysis is its unwillingness to accept that unconscious conflict influences behaviour. With theoretical and clinical arguments, the author argues that unconscious factors must be taken in to understand and to treat the child. Countertransference, often cumbersome with neuropsychiatric children, becomes easier to handle if the analyst is clear about his field of investigation. If he sees through simplistic formulations on aetiology, countertransference gets even more manageable. Psychoanalysis can result in considerable intellectual and emotional development, as illustrated by work with a latency boy with DAMP, autism and slight mental retardation. In his psychoanalytic theoretical framework of the case, the author unites ego-psychological formulations with a Bionian conceptualisation of the thought disturbance.     

Electrophysiology in neuropsychiatric research: a network perspective

A growing number of anatomic and physiologic studies have shown that parallel sensory and motor information processing occurs in multiple cortical areas. These findings challenge the traditional model of brain processing, which states that the brain is a collection of physically discrete processing modules that pass information to each other by neuronal impulses in a stepwise manner. New concepts based on neural network models suggest that the brain is a dynamically shifting collection of interpenetrating, distributed, and transient neural networks. Neither of these models is necessarily mutually exclusive, but each gives different perspectives on the brain that might be complementary. Each model has its own research methodology, with functional magnetic resonance imaging supporting notions of modular processing, and electrophysiology (eg, electroencephalography) emphasizing the network model. These two technologies might be combined fruitfully in the near future to provide us with a better understanding of the brain. However, this common enterprise can succeed only when the inherent limitations and advantages of both models and technologies are known. After a general introduction about electrophysiology as a research tool and its relation to the network model, several practical examples are given on the generation of pathophysiologic models and disease classification, intermediate phenotyping for genetic investigations, and pharmacodynamic modeling. Finally, proposals are made about how to integrate electrophysiology and neuroimaging methods.
