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.
The electroencephalogram (EEG) is a recording of the electrical activity of the brain from the scalp. The recorded waveforms reflect the cortical electrical activity. Signal intensity: EEG activity is quite small, measured in microvolts (mV). Signal frequency: the main frequencies of the human EEG waves are: 1  Delta: has a frequency of 3 Hz or below. 2  Theta: has a frequency of 3.5 to 7.5 Hz and is classified as slow activity. 3  Alpha: has a frequency between 7.5 and 13 Hz.  Beta: beta activity is fast activity.
