Studies evaluate that 50% of people with diabetes will develop neuropathy. Diabetic nerve injury is impairment of a single solitary nerve (also named mononeuropathy). Com- monly 2 cranial nerves Viz., cranial nerve VII and cranial nerve VI are involved in facial nerve palsies. The former one is called Bell’s palsy and is acute Lower Motor Neuron facial nerve paralysis (>80%) causing an inability to control facial muscles on the affected side. The later one is sixth nerve palsy, (the abducens nerve), which is responsible for triggering contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye resulting in double vision on the affected side. In recent times, we have found to our amazement, rapid restoration of normalcy within a few hours to a few days, of Cranial Nerve palsies in diabetic subjects at our centre. We are presenting a group of cases having Type2DM over different time periods from 6 to 20 years and those who suddenly suffered facial nerve palsy and they came to VHSDRC for treatment. They were started on the new modality called the Dynamic Acupuncture Mediated Meta-physical Energy Therapy (DAMM Therapy), to recover from the facial palsy. The DAMM therapy is a unique novel way of infusing and transferring healing energy from the therapist to the patient. Within 2 - 7 sittings of DAMM therapy patients showed 75% - 100% improvement in their clinical condition. 展开更多

Type 1 diabetes is classically the true form of insulinopaenic diabetes usually occurring in young children below the age of 15 years and occasionally up to 20 years and characterised by very low/ negligible fasting C-peptide in their blood due to extensive irreversible Beta cell damage. T1DM probably accounts for 5% to 10% of all diagnosed diabetes. The worldwide prevalence of T1DM is 0.1% to 0.3%, with 78,000 new cases every year, especially among young individuals (15. Type I diabetes is very much lower (20 times) in countries like Japan and India, than the western countries. The European Nicotinamide Diabetes Intervention Trial (ENDIT) is focused on the use of nicotinamide in the prevention of diabetes. In high doses (nicotinamide), it may cause a degree of sedation, a feeling of depression, and in very large dosages, liver toxicity. Because the vitamin cannot be marketed as a drug, the study is not getting a great deal of support from pharmaceutical companies. GAD antibodies (GADA) are a major diagnostic marker for Type 1 diabetes. Phase II clinical trials of a vaccine containing alum and recombinant GAD65, an auto antigen involved in type 1 diabetes, were promising, as of 2014 Phase III trial had failed. In our quest for improving the clinical condition & quality of life of type I DM & also to reduce the economic burden on them, we have embarked on a novel metaphysical energy therapy which we have been trying for the past 3 years at our research Centre. We have so far treated some 15 cases with this DAMM therapy. Among the 15 cases, 6 cases have shown significant improvement in fasting C-peptide levels. With the advent of this new modality of treatment (DAMM Therapy) the cost of treatment will be greatly reduced. This DAMM Therapy apparently has no side effects. This mode of treatment will open a new light in the world of Type I diabetes. 展开更多
