Amphetamines in the treatment of Parkinson's disease. (1/24)
Twenty-two patients with Parkinsonism were treated with levoamphetamine and 12 of these with dextroamphetamine. Levoamphetamine resulted in a significant improvement in disability from Parkinsonism, although the reduction in total disability, tremor, akinesia, and rigidity scores was slight (ca 20 percent). Dextroamphetamine in lower dosage also reduced disability by some 17 percent. The most disabled patients, including those also on levodopa, showed the greatest response to amphetamines. Previously, amphetamines have been reported to be a selective treatment for the oculogyric crises of post-encephalitic Parkinsonism. Amphetamines are thought to cause the release of catecholamines from central neurones. Their action in Parkinson's disease may be limited because of pre-existing striatal dopamine deficiency. Side-effects of amphetamines, anorexia, and CNS stimulation are different from those caused by levodopa in patients with Parkinson's disease. (+info)Encephalitis lethargica syndrome: 20 new cases and evidence of basal ganglia autoimmunity. (2/24)
In 1916, von Economo first described encephalitis lethargica (EL), a CNS disorder presenting with pharyngitis followed by sleep disorder, basal ganglia signs (particularly parkinsonism) and neuropsychiatric sequelae. Since the 1916-1927 epidemic, only sporadic cases have been described. Pathological studies revealed an encephalitis of the midbrain and basal ganglia, with lymphocyte (predominantly plasma cell) infiltration. The EL epidemic occurred during the same time period as the 1918 influenza pandemic, and the two outbreaks have been linked in the medical literature. However, von Economo and other contemporary scientists thought that the 1918 influenza virus was not the cause of EL. Recent examination of archived EL brain material has failed to demonstrate influenza RNA, adding to the evidence that EL was not an invasive influenza encephalitis. By contrast, the findings of intrathecal oligoclonal bands (OCB) and beneficial effects of steroid treatments have provoked the hypothesis that EL may be immune-mediated. We have recently seen 20 patients with a similar EL phenotype, 55% of whom had a preceding pharyngitis. The patients had remarkable similarity to the historical descriptions of EL: sleep disorder (somnolence, sleep inversion or insomnia), lethargy, parkinsonism, dyskinesias and neuropsychiatric symptoms. CSF examination commonly showed elevated protein and OCB (75 and 69% respectively). Investigation found no evidence of viral encephalitis or other recognized causes of rapid-onset parkinsonism. MRI of the brain was normal in 60% but showed inflammatory changes localized to the deep grey matter in 40% of patients. We investigated the possibility that this phenotype could be a postinfectious autoimmune CNS disorder, and therefore similar to Sydenham's chorea. Anti-streptolysin-O titres were elevated in 65% of patients. Furthermore, western immunoblotting showed that 95% of EL patients had autoantibodies reactive against human basal ganglia antigens. These antibodies were also present in the CSF in four patients tested. By contrast, antibodies reactive against the basal ganglia were found in only 2-4% of child and adult controls (n = 173, P < 0.0001). Rather than showing polyspecific binding, these antibodies bound to common neural autoantigens of molecular weight 40, 45, 60 and 98 kDa. Regional tissue comparisons showed that the majority of these autoantigens were specific to or enriched in CNS tissue. Immunohistochemistry with secondary staining localized antibody binding to neurons rather than glial populations. Further investigation is required to determine whether these antibodies affect neuronal function (i.e. whether they are pathogenic anti-neuronal antibodies). Histopathology in one case demonstrated striatal encephalitis with perivenous B- and T-lymphocytic infiltration. We believe an EL-like syndrome is still prevalent, and propose that this syndrome may be secondary to autoimmunity against deep grey matter neurons. (+info)Steroid-responsive encephalitis lethargica syndrome with malignant catatonia. (3/24)
We report a 47-year-old man who is considered to have sporadic encephalitis lethargica (EL). He presented with hyperpyrexia, lethargy, akinetic mutism, and posture of decorticate rigidity following coma and respiratory failure. Intravenous methylprednisolone pulse therapy improved his condition rapidly and remarkably. Electroencephalography (EEG) showed severe diffuse slow waves of bilateral frontal dominancy, and paralleled the clinical course. Our patient fulfilled the diagnostic criteria for malignant catatonia, so we diagnosed secondary malignant catatonia due to EL syndrome. The effect of corticosteroid treatment remains controversial in encephalitis; however, some EL syndrome patients exhibit an excellent response to corticosteroid treatment. Therefore, EL syndrome may be secondary to autoimmunity against deep grey matter. It is important to distinguish secondary catatonia due to general medical conditions from psychiatric catatonia and to choose a treatment suitable for the medical condition.

When opened as a post-graduate teaching and research hospital in 1923, the Maudsley made virtually no provision for the treatment of children. Yet its children's department saw sustained growth during the interwar period. This expansion is explored in relation to novel behaviourist hypotheses and the forging of formal links with local government and charitable bodies. The recruitment of psychologists, educators and specialist social workers fostered a multidisciplinary approach through case conferences. This development would structure the theoretical origins of child psychiatry, in particular influencing the role and interpretation of psychoanalytic theory within it. The theoretical orientation of child psychiatry and the practical treatment of children represented an area of dynamic change and innovation at a time when adult psychiatry struggled to discover effective treatments or achieve breakthroughs in causal understanding.

(+info)Postencephalitic Parkinson's disease (PEPD) is a secondary form of Parkinsonism that occurs as a result of viral encephalitis, most commonly following the 1918-1920 influenza pandemic. It is a rare condition today due to advancements in healthcare and vaccinations.
The infection causes inflammation in the brain, leading to damage in various areas, particularly the substantia nigra pars compacta, where dopamine-producing neurons are located. This results in decreased levels of dopamine, a neurotransmitter essential for smooth and controlled muscle movements.
The symptoms of PEPD can be similar to those seen in primary Parkinson's disease (PD), such as bradykinesia (slowness of movement), rigidity, resting tremors, and postural instability. However, there are some distinct differences between the two conditions:
1. Age at onset: PEPD tends to affect younger individuals, often in their 20s or 30s, while primary PD usually manifests in people over 50.
2. Symptom progression: The progression of symptoms in PEPD is typically more rapid and severe than in primary PD.
3. Non-motor symptoms: PEPD often presents with a wider range of non-motor symptoms, including sleep disturbances, mood changes, autonomic dysfunction, and oculogyric crises (involuntary upward deviation of the eyes).
4. Response to treatment: PEPD may not respond as well to levodopa therapy compared to primary PD, and patients often experience more severe side effects such as dyskinesias (abnormal involuntary movements) and motor fluctuations.
It is essential to differentiate between postencephalitic Parkinson's disease and primary Parkinson's disease, as the treatment approaches and prognosis may differ significantly.
Parkinson's disease is a progressive neurodegenerative disorder that affects movement. It is characterized by the death of dopamine-producing cells in the brain, specifically in an area called the substantia nigra. The loss of these cells leads to a decrease in dopamine levels, which results in the motor symptoms associated with Parkinson's disease. These symptoms can include tremors at rest, stiffness or rigidity of the limbs and trunk, bradykinesia (slowness of movement), and postural instability (impaired balance and coordination). In addition to these motor symptoms, non-motor symptoms such as cognitive impairment, depression, anxiety, and sleep disturbances are also common in people with Parkinson's disease. The exact cause of Parkinson's disease is unknown, but it is thought to be a combination of genetic and environmental factors. There is currently no cure for Parkinson's disease, but medications and therapies can help manage the symptoms and improve quality of life.
