The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

People with Parkinson's exhibit increased arm swing during early stages

People with Parkinson's disease swing their arms asymmetrically -- one arm swings less than the other -- when walking. This unusual movement is easily detected early when drugs and other interventions may help slow the disease, according to Penn State researchers who used inexpensive accelerometers on the arms of Parkinson's disease patients to measure arm swing.

Nearly half of children with epilepsy experience adverse events due to invasive EEG

Some type of adverse event occurs in nearly half of children with severe epilepsy undergoing invasive electroencephalography (EEG) recordings, reports a study in the December issue of Operative Neurosurgery, a quarterly supplement to Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

New exercise and memory study for Parkinson's disease patients

Researchers from the University of Maryland School of Medicine and the Baltimore VA Medical Center have launched a study of exercise and computerized memory training to see if those activities may help people with Parkinson's disease prevent memory changes. The type of memory that will be examined is known as "executive function;" it allows people to take in information and use it in a new way.

Matrix protein tenascin C regulates astrocyte development

How astrocytes, certain cells of the nervous system, are generated was largely unknown up to now. Bochum's researchers have now investigated what influence the cell environment, known as the extracellular matrix, has on this process.

Brain atrophy is evident in Parkinson's patients with MCI

Atrophy in the hippocampus, the region of the brain known for memory formation and storage, is evident in Parkinson's disease (PD) patients with cognitive impairment, including early decline known as mild cognitive impairment (MCI), according to a study by researchers in the Perelman School of Medicine at the University of Pennsylvania.

Intertwined diseases may both contribute to cognitive decline in Parkinson's

A method of classifying brain atrophy patterns in Alzheimer's disease patients using MRIs can also detect cognitive decline in Parkinson's disease, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania. Researchers also found that higher baseline Alzheimer's patterns of atrophy predicted long-term cognitive decline in cognitively normal Parkinson's patients.
