Embodiment

[0072] figure 1 It is a structural diagram of the room which shows one Example of this invention.

[0073] The room 10 of this embodiment is provided with a light irradiation device 20 for improving dementia symptoms and depression symptoms. The light irradiation device 20 gives light stimulation to the retinas of people in the room through the continuous flickering of the light source 21 . The light source 21 only needs to have an illuminance that can be sensed by retinal cells, and does not necessarily have to be an illuminance that can be recognized by people in the room. Continuous blinking of the light source 21 is controlled by the blinking control unit 22 . The blinking control unit 22 performs blinking by changing the frequency of the commercial power supply to, for example, 1 to 10 Hz. The frequency used for blinking is more preferably 2 to 9 Hz. If the flickering frequency is lower than 1 Hz, the synaptic transmission is inhibited, and the inhibitory response is ...

Abstract

A light exposure device (20) for improving cognitive symptoms and depression symptoms is characterized in imparting photostimulation to the retina by continuous flashing of a light source (21) at a frequency of 1 to 10 Hz and by photostimulation, inducing the continuous expression of Homer 1a and activation of the BK-type potassium channels in pyramidal cells of the cerebral cortex. It is possible to realize the same effect as the depression symptom-improving effect of an electroconvulsive stimulation device, and the same effect as the depression symptom-improving effect and cognitive symptom-improving effect of a transcranial magnetic stimulation device, and can be used in a home environment when compared to electroconvusion stimulation devices and transcranial magnetic stimulation devices that are limited being used for treatment at a medical institution.

Description

technical field [0001] The present invention relates to a light irradiation device capable of improving dementia symptoms and depression symptoms, a room provided with the light irradiation device, and a lighting fixture capable of improving dementia symptoms and depression symptoms. Background technique [0002] Cognitive-behavioral therapy (improving the way of thinking) that does not use drugs or therapeutic equipment is available as an initial treatment for depression, but it is not always effective. For effective treatment, drug therapy is used. However, only half of the cases are successfully treated with just one medicine. More than half of them are combined use of multiple drugs, or are all drug resistant (Non-Patent Document 1). [0003] Electroconvulsive therapy (ECT) is relied upon in the case of major depressive disorder, such as drug-resistant depression, and depression with intense suicidal thoughts. The effectiveness of the therapy is widely recognized amon...
