We irradiated LPL on two patients with dementia of Alzhemer type and one patient with alcoholic dementia after obtaining informed consent from the patients and their families. The results were analyzed for clinical symptoms and changes in SPECT.
LPL therapy was used for this study in which a total of four sites: the forehead, the right and left temples, and the occiput were irradiated. The irradiation time was two minutes per site (10_m, watts), and the number of irradiation was two to four times per 1 week. To clearly determine whether therapeutic effects were attributed to this laser therapy, the following factors were set: Circumstances were fixed for a month, and medication was kept to the minimum necessary level. Under these conditions, the following was observed: symptoms of dementia advanced gradually in the chronic stage prompting the patient's care to last more than three months. Among the changes in clinical symptoms common among the patients were fewer emotional disturbances and slight improvement in short and middle term memory disturbances.
A comparison of the first SPECT just before laser therapy with SPECT conducted one to three months after laser therapy clearly showed improvement in only one patient. In the patient who showed improvement in SPECT, improvement in blood circulation was observed in the order of the basal nucleus, the thalamus, the lower part of the frontal lobe and the temporal lobe.
