Osteoporosis is a condition in which your bones break down faster than they regrow. Treatment usually includes a combination of medications and lifestyle changes. The most aggressive way to prevent bone loss is to take prescription medications.
To this point, direct examination of brain activity as a window into the clientâs mind has remained elusive. But advances in the field of brain examination using electroencephalographs (EEGs) may be changing all that. The first EEG was developed in the 1920âs by the German psychiatrist Hans Berger. He developed it to test the biological electricity produced in the brain, and first used it during brain surgery performed in 1924 on a 17-year-old boy.
Each complete cycle takes about an hour and a half. A group of researchers proposed in 1937 that the cycle be divided into 5 stages identifiable in the EEG record, labeled A through E. Now these stages are labeled 1 to 4, with the fifth being REM sleep. Some researchers refer to the wakefulness before sleep as stage 0.
