DMAE 250 mg by Thompson

LIKELY INEFFECTIVE

• Alzheimer disease. Oral deanol does not appear to improve memory in individuals with Alzheimer disease. Details: Two very small clinical trials in patients with Alzheimer disease show that taking deanol, titrated up to a dose of 600 mg three times daily, for 4-5 weeks does not seem to improve memory or other cognitive functions when compared with placebo (1680,1681).
• Tardive dyskinesia. Oral deanol does not improve symptoms of tardive dyskinesia. Details: Meta-analyses and individual clinical studies show that taking deanol 1-2 grams daily for up to 1 month does not improve symptoms of tardive dyskinesia when compared with baseline or placebo (1672,1673,1674,1675,1676,1803,1804).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aging. Although there has been interest in using oral deanol to prevent aging and extend life span, there is insufficient reliable information about the clinical effects of deanol for this purpose.
• Aging skin. Although there has been interest in using topical deanol for aging skin, there is insufficient reliable information about the clinical effects of deanol for this purpose.
• Athletic performance. Oral deanol has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy males shows that taking deanol in combination with ginseng, vitamins, and minerals for 6 weeks improves exercise performance by increasing total work load and maximal oxygen consumption during exercise (1671). It is unclear if these findings are due to deanol, other ingredients, or the combination.
• Attention deficit-hyperactivity disorder (ADHD). It is unclear if oral deanol is beneficial in children with ADHD. Details: Clinical research on the use of deanol in children with ADHD-like symptoms is mixed (1669,1677,1679,92702). One moderate sized clinical study in children with behavioral and learning disorders, most of whom also had hyperactivity, shows that taking deanol 500 mg daily for 3 months significantly improves performance on various psychometric tests when compared with placebo. The improvements seen with deanol were similar to those reported with methylphenidate 40 mg daily (1679). Another small study in children 6-12 years of age with behavior problems consistent with ADHD shows that taking deanol 300-500 mg daily for 12 weeks improves some measures of performance when compared with placebo (92702). However, other research shows that deanol does not improve ADHD symptoms in children (1669,1677). The children evaluated in each of these studies were not diagnosed with ADHD using current diagnostic guidelines, limiting the applicability of these results in clinical practice.
• Autism spectrum disorder. Although there has been interest in using oral deanol for autism spectrum disorder, there is insufficient reliable information about the clinical effects of deanol for this purpose.
• Cognitive function. Although there has been interest in using oral deanol to improve cognitive function, there is insufficient reliable information about the clinical effects of deanol for this purpose. More evidence is needed to rate deanol for these uses.

POSSIBLY SAFE ...when used orally and appropriately. Deanol has been safely used at doses up to 2 grams daily for up to 4 weeks and doses up to 500 mg daily for up to 3 months (1668,1671,1672,1673,1674,1675,1676,1679,1680,1681). There is insufficient reliable information available about the safety of deanol when used topically.

PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.

General ...Orally, deanol seems to be well tolerated (1668,1671,1672,1673,1674,1675,1676,1679,1680,1681). However, deanol has been reported to cause constipation, diarrhea, urticaria, headache, drowsiness, insomnia, overstimulation, lucid dreams, confusion, motor retardation, depression, hypomania, and an increase in schizophrenia symptoms (1674,1680,1684,1685,1686,2706).
Most Common Adverse Effects:
Orally: Abdominal cramps, abdominal pain, diarrhea, drowsiness, nausea, vomiting.

Cardiovascular ...Orally, small elevations in blood pressure have been reported in some patients taking deanol up to 1800 mg daily. These effects improved after deanol discontinuation (1680).

Gastrointestinal ...Orally, deanol has been reported to cause diarrhea, abdominal cramps, abdominal pain, nausea, and vomiting (1674,1680).

Musculoskeletal ...Orally, deanol up to 1800 mg daily has been reported to cause motor retardation in a small number of patients. This effect improved after deanol discontinuation (1680).

Neurologic/CNS ...Orally, deanol has been reported to cause drowsiness, apathy, and confusion (1674,1680). In one case report, a physician promoted the use of deanol to induce lucid dreams, which may be considered an undesirable outcome for some patients (1686).

Psychiatric ...Orally, taking deanol at doses greater than 1000 mg daily has been reported to cause mood changes, including depression and hypomania, in patients with psychiatric conditions (1685). Deanol 1500 mg daily has been reported to increase schizophrenic symptoms in patients with chronic schizophrenia (1674).
