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.

Neuromodulation Options and Patient Selection for Parkinson's Disease.

Neuromodulation therapies, including deep brain stimulation (DBS) and pump therapies, are currently the standard of care for PD patients with advanced disease and motor complications that are difficult to control with medical management alone. The quest for alternate lesser invasive approaches led to the development of several novel therapies like intrajejunal levodopa infusions (IJLI), continuous subcutaneous apomorphine infusions (CSAI) and Magnetic Resonance guided Focused Ultrasound (MRgFUS) in recent years. To achieve good outcomes with any of these therapeutic modalities, careful patient selection, multidisciplinary evaluation and technical expertise are equally important.

Discovery of familial cerebral cavernous malformation in a Saudi population.

Familial cerebral cavernous malformation is a rare entity. It has been described commonly among the Hispanic population and sparsely among the Italian, French, Swedish and Chinese populations. We discovered two families with this condition among the Saudi population for the first time.
