Parkinson's Disease: Overview01:15

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's Disease: Treatment01:24

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...
Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Visual Agnosia01:12

Visual Agnosia

Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round end"...

Area of Science:

  • Neuroscience
  • Neurology
  • Motor Control

Background:

  • Apraxia is defined as difficulty with learned, skilled gestures.
  • This review focuses on ideomotor limb apraxia, a specific type of apraxia.
  • Understanding apraxia is crucial for diagnosing and managing neurological disorders.

Purpose of the Study:

  • To describe the range of motor impairments classified as apraxia.
  • To present models explaining the difficulties seen in patients with apraxia.
  • To discuss the neural network underlying praxis and its relation to specific diseases.

Main Methods:

  • Literature review of apraxia and related motor control studies.
  • Analysis of prominent theoretical models of praxis.
  • Discussion of neuroanatomical networks implicated in apraxia.

Main Results:

  • Apraxia encompasses a spectrum of motor impairments, with ideomotor limb apraxia being a key focus.
  • Several models exist to explain the varied presentations of apraxia.
  • A large-scale frontal-parietal-basal ganglia network is implicated in praxis.

Conclusions:

  • Limb apraxia frequently occurs in corticobasal degeneration.
  • Corticobasal degeneration is a neurodegenerative condition affecting frontal, parietal, and basal ganglia regions.
  • Understanding the neural basis of apraxia aids in understanding neurodegenerative diseases.
