Insights

Locomotion disorders worsen in early Huntington's disease (HD). Gait initiation and performance decline, linked to initial functional capacity and motor impairment severity in HD patients.

Area of Science:

  • Neurology
  • Movement Disorders
  • Huntington's Disease Research

Context:

  • Locomotion disorders are a significant feature of Huntington's disease (HD).
  • The progression of gait and gait initiation issues in early-stage HD is not well understood.
  • Previous studies focused on motor, functional, or cognitive changes, leaving a gap in understanding locomotion evolution.

Purpose:

  • To quantify the rate of progression for gait and gait initiation disorders in Huntington's disease.
  • To identify factors correlating with the evolution of locomotion deficits in early HD.
  • To analyze changes in anticipatory postural adjustments (APA), gait speed, stride time, and stride length.

Summary:

  • Evaluated 18 HD patients over at least one year, assessing APA, gait speed, stride time, and stride length.
  • Observed worsening in APA, correlating with akinesia, and decreased gait speed due to increased stride time and reduced stride length.
  • Stride-to-stride variability remained stable, but gait initiation and performance deteriorated.

Impact:

  • Demonstrates a clear progression of gait and gait initiation problems in early HD.
  • Suggests that lower initial functional capacity and greater motor impairment predict faster locomotion decline in HD patients.
  • Provides crucial data for understanding disease progression and developing targeted interventions for HD-related movement disorders.

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Parkinson's Disease: Overview

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...

Parkinson Disease l: Introduction

Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of which...

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of its...
