Serum lipid profile among sporadic and familial forms of Parkinson's disease.

Brain cholesterol metabolism has been described as altered in Parkinson's disease (PD) patients. Serum lipid levels have been widely studied in PD with controversial results among different populations and age groups. The present study is aimed at determining if the serum lipid profile could be influenced by the genetic background of PD patients.

Intracranial calcifications associated with epilepsy: A case report of lipoid proteinosis.

Lipoid proteinosis (LP) is a very rare autosomal-recessive disease characterized by multisystem involvement due to intracellular deposition of amorphous hyaline material. Clinical manifestations include hoarness, acne-like facial scarring and neurological manifestation including seizures. We describe the clinical, genetics and radiological features of LP in a refractory epileptic patient with genetic confirmation.

Increased bilirubin levels in Parkinson's disease.

Introduction: Oxidative stress plays a key role in Parkinson's disease (PD) etiopathology. Heme oxygenase, an important enzyme which regulates oxidative balance, converts heme molecules into carbon monoxide, iron and biliverdin/bilirubin. The role of bilirubin has not been fully studied in PD, showing controversial results over the last few decades.

Clinical, genetic and neuropathological characterization of spinocerebellar ataxia type 37.

The autosomal dominant spinocerebellar ataxias (SCAs) consist of a highly heterogeneous group of rare movement disorders characterized by progressive cerebellar ataxia variably associated with ophthalmoplegia, pyramidal and extrapyramidal signs, dementia, pigmentary retinopathy, seizures, lower motor neuron signs, or peripheral neuropathy. Over 41 different SCA subtypes have been described evidencing the high clinical and genetic heterogeneity. We previously reported a novel spinocerebellar ataxia type subtype, SCA37, linked to an 11-Mb genomic region on 1p32, in a large Spanish ataxia pedigree characterized by ataxia and a pure cerebellar syndrome distinctively presenting with early-altered vertical eye movements.
