Choroideremia (/ k ɒ ˌ r ɔɪ d ɪ ˈ r iː m i ə /; CHM) is a rare, X-linked recessive form of hereditary retinal degeneration that affects roughly 1 in 50,000 males. The disease causes a gradual loss of vision, starting with childhood night blindness, followed by peripheral vision loss and progressing to loss of central vision later in life.
Treatment consists of three phases of immunotherapy: 1. Acute phase: IV steroids (methylprednisolone 1 mg/kg) for 3–5 days or plasmapheresis are given to restore visual function. [3] 2. Intermediate phase: Oral steroids (typically prednisone 1 mg/kg) with taper are given to stabilize vision. [3] 3.
Choroideremia-deafness-obesity syndrome This condition is inherited in an X-linked recessive manner. Ayazi syndrome (or Chromosome 21 Xq21 deletion syndrome ) [ 1 ] is a syndrome characterized by choroideremia , congenital deafness and obesity .
“The brain undergoes many changes associated with aging, and one of them is the shrinkage of what we call the outer layer of the brain, or the cortex,” Emily Rogalski, professor of neurology ...
The brain is very complex, and is composed of many different areas and types of tissue, or matter. The different functions of different tissues in the brain may be more or less susceptible to age-induced changes. [6] The brain matter can be broadly classified as either grey matter, or white matter.
The brain plays a big part in the aging process, and scientists think they’ve pinpointed the specific cells that control it.. In a study of mice, researchers at the Allen Institute identified ...
Dementia is a devastating condition that impacts up to 10 percent of older adults. And while there's no cure, getting diagnosed early can help patients get on a treatment plan and families prepare ...
A subdural hygroma (SDG) is a collection of cerebrospinal fluid (CSF), without blood, located under the dural membrane of the brain. Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma.
