Effect Of DHEA On Drug Abuse Treatment

Preclinical rodent studies have shown that DHEA markedly improves resistance to cocaine’s initial effects, and prevents relapse to its use (1,2).

In addition, DHEA increases neurogenesis and neuronal survival in human neural stem cells cultures (3);  this is important because high dosage cocaine decreases neurogenesis in the brain, and impairs working memory in rats (4).

DHEA also appeared to contribute to the success of outcomes in addiction treatment of humans:

DHEA complementary treatment was effective in heroin addicts, showing significant improvement in the severity of withdrawal symptoms, depression and anxiety scores (providing subjects had not previously used cocaine or benzodiazepines, and had experienced few withdrawal programs) (5).

Moreover, a double-blind, placebo-controlled study in adult polydrug users in a detoxification program showed the efficacy of DHEA treatment combined with psychosocial enrichment and after-care.  DHEA administration positively affected decision-making, mood and well-being as early as one month into treatment, and had a long-lasting preventive effect on relapse to drug use. The DHEA treated subjects reported fewer negative emotions, and showed more advantageous choosing in a decision-making task (Figure 1). Furthermore, in a 16-month follow-up, relapse rates of DHEA-treated subjects were only 11.5% (Figure 2). No adverse symptoms were found. These findings demonstrate the long-term effect of DHEA on drug relapse.

DHEA Program

Our program revealed that for optimal efficacy and outcome, DHEA must be taken at adequate, individually tailored doses. Therefore, we developed a novel algorithm, which takes into account personal data (age, gender, ethnicity, previous drug consumption, diseases, etc.) and various physical and psychological parameters, and calculates the optimal dose of DHEA and length of treatment required. Our software also provides a personal profile for each patient, through which the caregiver can monitor the patient’s progress, manage the course of treatment, and even predict the length of treatment needed and probability to relapse. Our treatment program is an add-on treatment that can be easily integrated into existing rehab programs and enhance the various therapies given. Our group of skilled specialists will be at your service throughout the treatment process, and will promptly respond to every question or concern. 

DHEA in Humans

DHEA is a steroidal pro-hormone, naturally produced from cholesterol. DHEA synthesised in the brain functions as a neurosteroid. DHEA is the most abundant circulating steroid hormone in humans, although its secretion changes across the lifespan. Its natural production in the body begins at the age of 7 and peaks at the age of 25, followed by a steady decline in production; by the age of 75, it is at ~20% of its peak amount. DHEA is essential for the immunological system and was shown to help prevent various diseases, including high blood pressure, diabetes, and autoimmune disorders. DHEA was also found to boost energy, improve mood and well-being, decrease depression and anxiety, and also have an anti-aging effect [1, 2].  DHEA may have weak side effects, e.g., transient increase in hepatic enzymes, increased perspiration, oily facial skin or increased facial hair, abdominal pain, sleep disturbances, rash, or breast sensitivity. These transient effects were seen mostly at higher doses of 100-200 mg per day given for 12-24 weeks [3, 4]; as for longer periods of 10-12 months (at 50 mg DHEA), either slight or no serious adverse events were reported [5, 6].   For treatment of addiction, DHEA is generally taken at the higher doses, and therefore patients require tight supervision, including weekly data collection and analysis, and possible alterations of DHEA dosage accordingly.
