Disorders of the Nervous Tissue01:28

Disorders of the Nervous Tissue

3.1K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.

Equilibrium and Balance01:15

Equilibrium and Balance

8.0K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Gastrointestinal Motility Disorders01:20

Gastrointestinal Motility Disorders

1.5K
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Muscles that Move the Head01:19

Muscles that Move the Head

6.9K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

2.3K
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...

Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

2.4K
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...

Summary
This summary is machine-generated.

Cranial movement disorders are often overlooked in functional neurological symptoms. Recognizing specific signs like convergence spasms is key for accurate diagnosis and management of these under-recognized conditions.

Area of Science:

  • Neurology
  • Neuroscience

Background:

  • Functional neurological symptoms are common in neurological practice.
  • Cranial movement disorders (eyes, face, jaw, tongue, palate) are an under-recognized feature of functional neurological disorders.
  • Existing research on functional neurological disorders has not sufficiently addressed cranial movement disorders.

Purpose of the Study:

  • To increase awareness and understanding of cranial functional movement disorders.
  • To highlight the diagnostic significance of positive clinical signs in these disorders.
  • To emphasize the importance of differential diagnosis for accurate and timely management.

Main Methods:

  • Review of clinical features of functional neurological disorders.
  • Identification of characteristic positive signs of cranial functional movement disorders.
  • Discussion of differential diagnoses including organic causes.

Main Results:

  • Cranial movement disorders can manifest independently or with other functional symptoms.
  • Specific signs like convergence spasms and unilateral platysmal spasm are indicative of functional disorders.
  • A broad differential diagnosis, including organic conditions like stroke, is crucial.

Conclusions:

  • Enhanced recognition of cranial functional movement disorders can aid in diagnosing functional neurological disorders.
  • Accurate diagnosis through understanding differential diagnoses is essential for preventing complications and guiding treatment.
  • Further research and tailored therapies are needed for these under-recognized conditions.
