The Bronowski Clinic

Clinical Support and its Ongoing Development

Consistent with the charter of the Bronowski Institute of Behavioural Neuroscience the staff of the Bronowski Clinic are devoted to disseminating their knowledge and experience to improve the quality of life in people with Parkinson’s disease and other disorders. To achieve this we provide professional support for medical doctors, psychologists, clinicians and other health professionals in their routine practice of treating any disorder that respond to the implementation of phototherapy.

We not only provide professional advice on strategic light use as an adjuvant treatment in Parkinson’s disease but we continue to explore other applications of this non-invasive treatment to help in other conditions such as the Parkinson’s Plus disorders, Multiple Sclerosis, insomnia, depression, Huntington’s chorea and Tourette’s Syndrome. We have also found many instances whereby the comorbid states of many disease that include insomnia and depression can be improved by strategic light therapy where drug intervention has failed.

We have also found that critical factors such as time of light administration during the day/night cycle, duration of treatment and technical aspects of light administration that have not been addressed to optimise chronotherapeutics. Consequently, are we are now refining the application of light therapy so as to compliment traditional approached to treatment of many disorders.

In doing so we are defining a new approach for developing best management practices for applying bright light therapy in the treatment of anxiety, depression and insomnia not only as comorbidities of Parkinson’s disease but also in other conditions as well as being treated as mental conditions in their own right.

In our most recent work, we have unveiled the therapeutic and adverse effects of phototherapy in such detail that we believe light should be regarded as a “drug” in that under dosing, effective dosing and overdosing can result in a response by patients much resembling that occurring with pharmacological intervention. This is particularly important when applying a new treatment to any disorder given that individual sensitivity to drugs can vary from patient to patient and strategic light therapy can elicit the same response.

We are also developing an approach for treating drug overdosing phenomena with strategic drug titration that will aid in reducing polypharmacy in drug addiction, drug over-prescription and also to reduce the need for invasive forms of surgical intervention, such as DBS.

We are currently developing a comprehensive guide describing the key to more effectively treating depression, insomnia and other neurological and psychiatric disorders using the chronotherapeutic approach. This will describe a description of long and short term methodologies for the application of bright light therapy for symptomatic treatment and even slowing the progression of desiderative disease states.

As a research clinic we welcome any person whom remains trouble by common derivatives of many complaints such as insomnia, depression or anxiety, whether they exist they in their own right or they be part of another, more complex disorder.

We are here to serve those who have a compromised quality of life and we will be pleased to provide what service we are able, no matter where you reside.

So please make contact, if you feel we may be of some help in improving your quality of life.
