In some cases, inherited genetic mutations cause temporal wasting, also known as frontotemporal lobar degeneration, but in most cases, the cause is unknown. Further research must be conducted to discover the true cause, according to the National Institute on Aging.Continue Reading
Scientists from the National Institute on Aging describe patterns of change in the brain seen in an autopsy after death, including loss of neurons and abnormal amounts or forms of proteins called tau and TDP-43. These proteins occur naturally in the body and help cells function properly. When the proteins do not work properly, for reasons not yet fully understood, damage occurs to neurons in specific brain regions.
Frontotemporal lobar disorders are grouped into three types that are defined by early symptoms. Behavioral variant frontotemporal dementia causes changes in personality, behavior, emotions and judgment. Primary progressive aphasia is characterized by changes in language ability, including speaking, understanding, reading and writing. Corticobasal syndrome, also known as supranuclear palsy or amyotrophic lateral sclerosis, is characterized by various difficulties with physical movement, including the use of one or more limbs, difficulty walking, frequent falls and poor coordination. Symptoms vary from one person to another and some symptoms are common to more than one disorder, making it difficult to identify which type of frontotemporal lobar disorder is present in the early stages of the disease.Learn more about Conditions & Diseases
In many cases, the exact cause for a rheumatic disorder is unknown by scientists. However, there are varying factors that can play a role in the development of a specific rheumatic disease type, such as genetics, wear and tear of joints, repetitive stress and infections, as noted by Johns Hopkins Medicine. Rheumatism is a term that encompasses different types of rheumatic disorders, including rheumatoid arthritis, osteoarthritis, gout, lupus and infectious arthritis.Full Answer >
In some cases, fluid on the lungs, or pleural effusion, is dealt with by treating the cause of the fluid build-up, such as pneumonia or congestive heart failure, according to WebMD. In urgent cases, doctors must drain the fluid. Other procedures address severe inflammation and prevent recurrence.Full Answer >
The primary cause of chronic obstructive pulmonary disease is smoking, and it is responsible for 80 to 90 percent of all cases, according to the American Lung Association. Toxic substances in cigarette smoke can narrow airways in the lungs, damage air sacs or alveoli and cause decreased defense against infection. Air pollution and fumes encountered at work can cause COPD as can a rare, inherited disorder called alpha-1 deficiency.Full Answer >
Sciatica may resolve within a matter of weeks in some cases, but may take as long as several months depending on the cause of the nerve compressions, reports Spine-health. Treatment for sciatica includes physical therapy, epidural injections and surgery. Heat or ice therapy may provide immediate relief.Full Answer >
