Disorders of the Nervous Tissue

Disorders of the Nervous Tissue

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.

Neural Regulation

Neural Regulation

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: Overview

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...

Parkinson's Disease: Treatment

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...

Summary

This summary is machine-generated.

Functional Neurological Disorders (FND) are common in hospitalized neurology patients, representing the third most frequent diagnosis. Inconsistent coding and reimbursement issues may contribute to neglect in healthcare for FND.

Neurology
Neuroscience
Healthcare Management

Background:

Functional Neurological Disorders (FND) are prevalent in specialized neurology clinics.
Limited research exists on the frequency of FND among neurology inpatients.

Purpose of the Study:

To determine the frequency of FND in hospitalized neurology patients.
To analyze demographic and clinical features of FND inpatients.
To investigate diagnostic coding and reimbursement patterns for FND.

Main Methods:

Prospective and retrospective case ascertainment over two years.
Analysis of demographic and clinical data.
Examination of reimbursement data.

Main Results:

FND was the presenting complaint in 5.7% (267/4648) of inpatients; 4.7% (217/4648) received a standalone FND diagnosis.
FND represented 2.4% of suspected stroke admissions, 11.8% of epilepsy workups, and 7.6% of emergency seizure admissions.
Inconsistent diagnostic coding of FND was linked to lower per-day revenue.

Conclusions:

FND is the third most common inpatient neurological diagnosis, yet is underrepresented in training, services, and research.
Stroke-like presentations and seizures are common FND forms in emergency admissions.
Reimbursement systems may discourage accurate FND coding, perpetuating healthcare neglect.
