Disorders of the Nervous Tissue

2.5K
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.
Parkinson's disease arises from the...

Alzheimer's Disease: Overview

1.6K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Dementia

498
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

1.7K
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 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.

Alzheimer's Disease: Treatment

772
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Area of Science:

  • Neuropathology
  • Cerebrovascular Diseases
  • Neurodegenerative Disorders

Context:

  • Dementing diseases encompass a wide spectrum, necessitating focused study on specific neuropathological and cerebrovascular conditions.
  • This review concentrates on amyotrophic lateral sclerosis with dementia (ALSD) and three unique vascular disorders contributing to dementia.

Purpose:

  • To describe the distinct neuropathological features of ALSD.
  • To elucidate the specific cerebral vascular pathologies associated with CARASIL, CADASIL, and Sneddon syndrome.

Summary:

  • ALSD exhibits unique cortical neuropathology, including ubiquitin-positive inclusions and degeneration in the hippocampal CA1-subiculum transition zone.
  • Cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL) shows intimal thickening in arteries, sparing scalp vessels.
  • Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) involves smooth muscle cell degeneration and granular material deposition in cerebral vessels.
  • Sneddon syndrome presents with sclerotic changes in deep perforating and main cerebral arteries, with relative sparing of meningeal vessels.

Impact:

  • Provides a detailed neuropathological and vascular comparison of key dementia-related diseases.
  • Enhances understanding of the underlying mechanisms in rare genetic and acquired cerebrovascular disorders causing dementia.
  • Offers a foundation for future research into targeted therapies for specific dementia subtypes.
