Novel de novo heterozygous CACNA1A gene variant in generalised dystonia: a case report.

Background: Dystonia is a genetic or non-genetic movement disorder with typical patterned and twisting movements due to abnormal muscle contractions that may be associated with tremor. Genetic and phenotypic heterogeneity leads to variable clinical presentation.

Methodology: Next-generation sequencing technologies are being currently used in the workup of patients with inherited dystonia to determine the specific cause in the individuals with autosomal dominant, recessive, X-linked or mitochondrial inheritance patterns.

Clinical Utility of Deutetrabenazine as a Treatment Option for Chorea Associated with Huntington's Disease and Tardive Dyskinesia.

Deutetrabenazine (DTBZ) is used for the treatment of tardive dyskinesia (TD) and chorea in Huntington's Disease (HD). Four pivotal clinical trials showed the efficacy of DTBZ in these conditions. Long term follow-up studies confirmed evidence of overall safety and continued efficacy of this drug.

Assessing the risks of treatment in Parkinson disease psychosis: An in-depth analysis.

Background: Parkinson disease (PD) psychosis (PDP) is a disabling non-motor symptom. Pharmacologic treatment is limited to pimavanserin, quetiapine, and clozapine, which do not worsen parkinsonism. A Food and Drug Administration black box warning exists for antipsychotics, suggesting increased mortality in elderly patients with dementia.

Early-Onset Alzheimer's Disease Masquerading as Catatonia.

A 35-year-old woman with a history of sexual trauma was brought in by her family for further evaluation of depressive symptoms and progressive decline in activities of daily living. She was admitted to the inpatient psychiatric unit for the treatment of suspected catatonia. After failure to respond to standard medical treatment, she received an extensive workup, which ultimately revealed a PSEN1 mutation consistent with early-onset Alzheimer's disease.

Hyperglycaemia-related occipital lobe seizures.

Recognition of the role of hyperglycaemia in seizures is vital, because they tend to refractory to antiepileptic drugs and respond to insulin therapy and hydration.

White matter damage, neuroinflammation, and neuronal integrity in HAND.

HIV-associated neurocognitive disorders (HANDs) persist even with virologic suppression on combination antiretroviral therapy (cART), and the underlying pathophysiological mechanisms are not well understood. We performed structural magnetic resonance imaging and MR spectroscopy (MRS) in HIV+ individuals without major neurocognitive comorbidities. Study participants were classified as neurocognitively unimpaired (NU), asymptomatic (ANI), mild neurocognitive disorder (MND), or HIV-associated dementia (HAD).
