Sleep disorders are broadly classified into dyssomnias, parasomnias, circadian rhythm sleep disorders involving the timing of sleep, and other disorders including ones caused by medical or psychological conditions. The most common sleep disorder is insomnia, to which there are both cognitive and physical causes which are addressed at IHM consecutively.

Essentially poor sleep quality is defined as not reaching stage 3 or stage 4 sleep which both have important restorative properties necessary for health.

When a person has trouble getting to sleep and hence awakening at a desired time, but has a normal sleep pattern once asleep, a Circadian disorder is likely the cause.

REM sleep disorder is a parasomnia and a predictor of neurodegenerative disease including prion like Synucleinopathy.

External audio and photonic stimulation have effects that can reduce sleep pathologies related to Insomnia, Circadian disorders and REM sleep disorders.


The Neuro-biophysical treatment at IHM uses a closed-loop method which employs electroencephalographic (EEG) data. EEG activity is monitored and modulates the audio and photonic stimulation. This approach provides concurrent real-time EEG training.

The application of this form of treatment requires a clinician for electrode placement and for stimulating frequency setting. The required frequencies are transmitted through sensory neural pathways to the thalamus and where the audio and visual sensory information is processed. From there, the activity is distributed throughout other limbic areas and the cerebral cortex via the cortical thalamic loop which produces the endogenous electrical response in the brain in relation to the frequency plus the mathematical representation of the stimulus per wave shape.


The risk of developing a sleep disorder in the elderly is especially increased for REM sleep behavior disorders, insomnia and circadian rhythm disturbances.

Insomnia has also shown to be 40% more common in women than in men, suggesting a hormonal imbalance especially during the perimenopausal years.

Over all, the treatment is experienced as relaxing for the patient. The effects are carried over to help the patient with going to sleep and duration of sleep at night and with improvements in memory and immune system health through recuperative sleep, thereby protecting against disease.

Studies confirm that the treatment produces both transient and lasting changes in the EEG.
