Alzheimer's disease is defined by the National Institutes of Health (NIH) as a degenerative brain disease. Most patients start exhibiting symptoms after they reach the age of 60. Alzheimer's disease affects the brain through exponentially greater...
The human brain can be anatomically divided into three main sections, or layers. The outermost part is called the forebrain (the prosencephalon); the middle layer is called the midbrain (the messancephalon); and the innermost part of the brain is...
The brain is made of many layers of tissue. There is a vast network of connections from one area of the brain to the other. The brain can be divided based on what functions it performs or what structure it is made of.
Alzheimer's disease is a neurological disease that is often confused with aging in its early stages, according to the National Institutes of Health (NIH). Finding effective testing methods is essential for detecting Alzheimer's disease early and...
The primary mode of controlling seizures due to conditions like epilepsy is drug therapy. Most patients experience excellent results with a single medication, but others may need a combination of drugs. According to MayoClinic.com, this process of...
According to the National Institute of Neurological Disorders and Stroke, dementia is common in older people. Elderly dementia--symptoms of cognitive and behavioral impairment--can be caused by some medications, health conditions such as lung...
If weight loss were easy, everyone would be their ideal size. Although we know that obesity can lead to heart disease and stroke, in many states more than 25 percent of the population is obese, according to the U.S. Centers for Disease Control and...
If you have attention deficit hyperactivity disorder--ADHD--your brain has distinctive patterns that are different from those of normal people. While ADHD brain "wiring" has created problems for you in paying attention, sticking with boring tasks,...
Serotonin is a neurotransmitter that has numerous physiological functions in the central nervous system. It is made from l-tryptophan, an essential amino acid found in many protein foods. Low serotonin levels in the brain occur from dietary...
The internal carotid artery provides blood supply to most of the brain's cortex on one side, including the frontal, parietal and temporal lobes. Only the posterior parts of the brain are supplied by different arteries. The internal carotid divides...
Stroke rehabilitation may include muscle relearning technique in situations where a stroke has caused reduced movement or partial paralysis. The success of rehabilitation following a stroke has many variables, such as the cause and severity and...

The human brain weighs only three pounds but is estimated to have about 100 billion cells, according to the clinical neuropsychologist Glen Johnson in his book "The Traumatic Brain Injury Survival Guide." As with other organs in the body, each...
Scientists liken the brain's terrain to a dense "neuron forest" populated by an astonishing 100 billion nerve cells, or neurons, and branches that connect at more than 100 trillion junctures. As signals flitter through that forest, thoughts are...
Nonepileptic seizures are those that mimic epileptic seizures but have another cause. Epileptic seizures are caused by dysfunctional neurological signals in the brain's cortex while nonepileptic episodes are spurred by a complicating medical...
Dementia itself is not a disease. According to Thomas D. Bird, writing in "Harrison's Principles of Internal Medicine," it is a deterioration in mental abilities that impairs the successful performance of activities of daily living. Memory is the...
Hearing a sound and detecting its origin sparks a complex cascade of neurological processes in areas of the brain responsible for discerning sound, vision and object location. Brain regions, such as the temporal cortex, occipital cortex, posterior...
The brain consists of different regions that have distinct functions but communicate with each other. The brain consists of the cerebral cortex, brain stem and cerebellum. The cerebral cortex is further broken down into four lobes: the frontal,...
Memory is a complex function that involves multiple steps, starting with the input of the stimulus to the brain and ending with independent memory retrieval. Georgia Tech states that human memory is made up of three basic stages: sensory memory,...
The brain can be divided in to several regions based on physiological characteristics and physical divisions. The central nervous system is generally broken into the fore-brain which includes the cerebrum, the mid- and hind-brain which include the...
Cerebral palsy is a disorder that begins in childhood. It is an umbrella term that covers a number of neurological disorders that stem from damage to the brain's cerebral cortex, which is associated with body movement and coordination. Medical...
Dementia is basically a loss of accurate mental functioning. Dementia is a broad term to describe various types of brain functioning degeneration that occurs within the lifetime of some individuals. Cognitive functioning is often severely...
Also known as aboulomania, pathological indecision can disrupt many areas of life. While most of us don't suffer from indecision to this extent, we may find ourselves overwhelmed by the increasing number of choices offered in modern life....
The cerebral cortex, which is responsible for language, senses, thinking and reasoning as well as other functions and abilities, begins to develop soon after conception. The National Institute of Neurological Disorders and Stroke states that "most...
The brain is an incredibly complex organ, responsible for managing everything from breathing and physical coordination to logic, language and artistic expression. While all animals have brains, they don't all possess the higher reasoning and...
