Alzheimer’s Disease and Caregiving

Overview

Frontotemporal Dementia

Definition

Frontotemporal dementia (FTD) is a degenerative condition of the front (anterior) part of the brain. It differs from other causes of dementia such as Alzheimer’s, Lewy body, and Creutzfeldt Jakob’s diseases. FTD is currently understood as a clinical syndrome that groups together Pick's disease, primary progressive aphasia, and semantic dementia. The areas of the brain affected by FTD—the frontal and anterior temporal lobes—control reasoning, personality, movement, speech, social graces, language, and some aspects of memory.

Hypoxic-Anoxic Brain Injury

Introduction and Definition

The brain requires a constant flow of oxygen to function normally. A hypoxic-anoxic injury, also known as HAI, occurs when that flow is disrupted, essentially starving the brain and preventing it from performing vital biochemical processes. Hypoxic refers to a partial lack of oxygen; anoxic means a total lack. In general, the more complete the deprivation, the more severe the harm to the brain and the greater the consequences.

Huntington's Disease

Definition

Huntington’s Disease (HD), also called Huntington’s chorea, is an inherited brain disorder that results in loss of physical control and mental capacity. Symptoms typically appear between the ages of 30 and 50, but may appear earlier or later. HD is characterized by progressive physical, cognitive, and psychological deterioration.

 

Brain Tumor

Introduction

A brain tumor is a collection of damaged cells that multiply out of control within the brain. Also called a neoplasm, growth, mass, or lesion, a brain tumor is classified as either primary or secondary (metastatic), and can be benign or malignant.

Stroke

Definition

A stroke is an injury to the brain caused when the brain's blood supply is interrupted or greatly reduced. The brain is deprived of oxygen and nutrients, and brain cells begin to die within minutes. For that reason, a stroke is considered a medical emergency and requires prompt diagnosis and treatment.
