Please see conventional, complementary, and alternative medical treatments for important background information regarding the different types of medical treatments discussed on this page. Naturopathic, Complementary, and Alternative treatments that may be considered include:
According to the Low Dose Naltrexone home page [LDN], LDN has been seen to benefit depression and bipolar disorder, so it is reasonable to consider LDN for cyclothymia as well. Dr. Weyrich has been trained to use Low Dose Naltrexone (LDN). However, Dr. Weyrich has not treated any cases of cyclothymia with LDN.
Please see What is Low Dose Naltrexone? for more information.
Neurofeedback has proven useful for treating depression [and thus dysthymia]. Dr. Weyrich has been certified in neurofeedback since 2008, and more recently completed an additional residency training program at ADD Clinic of Scottsdale, AZ. While at the ADD clinic, he treated numerous cases of depression.
Please see What is Neurofeedback? for more information.
Neuro Research [Hinz2015] reports that depression [and thus dysthymia] can be benefited by balancing neurotransmitter levels in the body.
Dr. Weyrich has been trained in neurotransmitter balancing protocols, but has not treated dysthymia or depression using this technique.
Please see What is Neurotransmitter Balancing? for more information.
