Objectives: The aim of the study was to describe the effects of aripiprazole, a new atypical antipsychotic drug that acts as a partial dopamine agonist on motor, behavioral and cognitive functions in patients with genetically confirmed Huntington's disease (HD).
Methods And Results: Three HD patients were evaluated for Unified Huntington Disease Rating Scale part I and II and Beck Depression Inventory at baseline, after two months and one-year treatment. Aripiprazole effectively controlled involuntary movements and psychiatric symptoms, with effects on cognitive functions.
Conclusions: Our case reports suggest that aripiprazole is well tolerated, remarkably improving some of the motor and behavioral symptoms in patients affected by HD. Randomized, controlled, long-term studies are warranted.

Background: There are no disease modifying therapies for Huntington's disease (HD), a rare but fatal genetic neurodegenerative condition. To develop and test new management strategies, a better understanding of the mechanisms underlying HD progression is needed. Aberrant changes in thalamo-cortical and striato-cerebellar circuitry have been observed in asymptomatic HD, along with transient enlargement of the dentate nucleus.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder characterized by a repeat of the cytosine-adenine-guanine trinucleotide (CAG) in the huntingtin gene (HTT). This results in the translation of a mutant huntingtin (mHTT) protein with an abnormally long polyglutamine (polyQ) repeat. The pathology of HD leads to neuronal cell loss, motor abnormalities, and dementia.

Objective: Electronic health record (EHR) systems contain a wealth of clinical data stored as both codified data and free-text narrative notes (NLP). The complexity of EHR presents challenges in feature representation, information extraction, and uncertainty quantification. To address these challenges, we proposed an efficient Aggregated naRrative Codified Health (ARCH) records analysis to generate a large-scale knowledge graph (KG) for a comprehensive set of EHR codified and narrative features.

Diabetes mellitus (DM) and neurodegenerative diseases/disturbances are worldwide health problems. The most common chronic conditions diagnosed in persons 60 years and older are type 2 diabetes mellitus (T2DM) and cognitive impairment. It was found that diabetes mellitus is a major risk for cognitive decline, dementia, Parkinson's disease (PD), Alzheimer's disease (AD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders.
