Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

1.6K
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...

Neural Regulation01:37

Neural Regulation

43.0K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Parkinson's Disease: Treatment

886
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...

Brainstem01:19

Brainstem

5.3K
The brainstem, located inferior to the brain and superior to the spinal cord, serves as a bridge between the cerebrum and the spinal cord. It plays a vital role in relaying information and controlling critical life functions. It comprises three primary regions: the midbrain, pons, and medulla oblongata.
The Midbrain
The midbrain is located beneath the diencephalon and connects the cerebrum with the lower parts of the brain. The cerebral peduncles are prominent midbrain structures that house the...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.6K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Prosopagnosia01:24

Prosopagnosia

626
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Area of Science:

  • Neurology
  • Geriatrics
  • Movement Disorders

Background:

  • Falls are a universal clinical feature and diagnostic criterion for progressive supranuclear palsy (PSP).
  • Despite their significance, the understanding of falls in PSP is limited, with few effective treatment options available.
  • Falls significantly impact the quality of life and independence of individuals with PSP.

Purpose of the Study:

  • To provide a comprehensive overview of falls in progressive supranuclear palsy.
  • To examine the impact, assessment, mechanisms, and management of falls in PSP.
  • To synthesize current literature and clinical experience regarding falls in PSP.

Main Methods:

  • Literature search using keywords "falls" and "progressive supran--nuclear palsy".
  • Inclusion of relevant known literature and synthesis with clinical practice experience.
  • Review of existing research on fall pathophysiology, assessment, and management.

Main Results:

  • Current understanding of fall pathophysiology in PSP highlights the roles of the indirect locomotor pathway and the pedunculopontine nucleus.
  • Shortcomings exist in commonly used assessments for measuring falls in PSP.
  • Both medical and nonmedical fall prevention strategies are discussed, alongside the challenge of balancing fall risk with promoting independence.

Conclusions:

  • Falls are central to the presentation and diagnosis of progressive supranuclear palsy.
  • Dysfunction in the indirect locomotor pathway and pedunculopontine nucleus is implicated as the neural basis for falls in PSP.
  • Current medical and nonmedical interventions for measuring and preventing falls in PSP are limited, advocating for a personalized management approach.
