By Robert Schinetsky

Data indicates that the prevalence of dementia among older adults roughly doubles every 5 years. It is expected that ~131 million adults worldwide are expected to be diagnosed with dementia by 2050.[1]

Additionally, an estimated 10% to 15% of individuals with mild cognitive impairment MCI go on to develop dementia each year.[2]

Currently, there is no cure for Alzheimer's dementia. There are just options for treating symptoms and attenuating the decline.

Common means of treating Alzheimer's are through the use of:

  • Acetylcholinesterase inhibitors (e.g. donepezil, etc.)
  • Choline precursors (e.g. Alpha-GPC, Choline Bitartrate, etc.)
  • N-methyl-d-aspartic acid (NMDA) receptor antagonists (e.g. memantine, namenda, etc.)

While much research centers around acetylcholine (the "learning neurotransmitter"), the results never met expectations, leading scientists to explore other neurotransmitters as a means of treating the disease.

One such neurotransmitter is norepinephrine (noradrenaline).

What is Norepinephrine and What Does it Do?

Norepinephrine is a catecholamine that functions in the brain and body as both a neurotransmitter and hormone.

It is made from dopamine in the brain and plays a key role in the body's "fight or flight" response.

Norepinephrine is important for alertness, arousal, and attention as well as helps maintain blood pressure during periods of stress.

It also impacts learning, memory, executive and inhibitory control.[3,4]

Noradrenaline & Dementia

A newly published meta-analysis and systematic review in the Journal of Neurology, Neurosurgery, and Psychiatry combed through 19 randomized control trials (that included a total of ~1300 patients) to assess the potential benefit of noradrenaline-enhancing compounds.[5]

Based on their analysis, the team of researchers concluded that "pharmacotherapies targeting the noradrenergic system can improve cognition and apathy" in individuals with dementia or mild cognitive impairment induced by Alzheimer's disease.[5]

One of the reasons that norepinephrine, in particular, was investigated as a route of treatments, is that apathy and lack of motivation are common features of Alzheimer's disease.

Researchers noted that while noradrenaline-focused pharmacotherapies could improve cognition and apathy, it did not seem to improve attention or episodic memory significantly.

Based on this it may be beneficial to test combination therapies involving both noradrenergic and cholinergic agents.

Something to keep in mind, though, is that many of the pharmaceuticals used to combat Alzheimer's dementia involve risks of their own.

For instance, drugs that target noradrenergic reuptake inhibition and agonism have the potential to increase heart rate, blood pressure and cardiac risk.

Additionally, acetylcholine-focused pharmacotherapies, such as donepezil, also have been known to lead to adverse effects, including GI distress, insomnia, and hypertension.[6]

Additional Concerns Regarding Choline Supplements

Choline supplements have gained considerable popularity in recent years, and have been seen in an ever-increasing number of pre workout supplements. The role of choline and depression is also being explored in various studies.

After all, choline is an essential brain nutrient, and since acetylcholine plays such a prominent role in cognition and learning, it's only natural that research has identified it as an important factor in Alzheimer's.

However, a recent 10-year cohort study including over 12 million individuals (50 years or older) indicated that the use of Alpha-GPC was significantly associated with a 10-year incident stroke risk in a dose-responsive manner.[7]

More specifically, individuals consuming alpha-GPC had a 46% higher risk of stroke compared to those who did not, which raises concerns about alpha gpc depression implications!

The reason for this increased risk of cardiovascular-related events may be due to TMAO -- a metabolite of choline, carnitine, and betaine metabolism.

Previous studies have shown that high levels of TMAO are associated with the risk of hemorrhagic stroke among patients with hypertension.

Something else to keep in mind is that certain forms of choline supplements seem to lead to higher increases in TMAO than others.

For example, choline bitartrate (the most common form of choline supplement) leads to 3x greater plasma levels of TMAO compared to phosphatidylcholine or no choline.[9] The choline in citicoline (CDP-choline) seems to be less prone to TMAO conversion.[12]

Eggs are a natural source of choline and seems to be a safer option for those that are concerned about the TMAO-cardiovascular incident connection.

Research has found that consuming two eggs per day for four weeks resulted in higher dietary and plasma choline concentrations, and improved markers of cardiovascular disease risk without affecting TMAO concentrations compared to an oatmeal breakfast.[10]

More recent research in healthy participants found that consuming 4 eggs daily showed no significant increase in TMAO or platelet reactivity. However, choline bitartrate supplements providing comparable total choline raised both TMAO and platelet reactivity, which could have implications for cdp choline depression management.[11]

The bottom line is that instead of looking for supplements to meet your choline requirements, obtaining it through the diet may be the safer route.

Norepinephrine, Not Serotonin for Depression

When you hear about depression, it's common to think of low serotonin levels. This association has been drilled home in pharmaceutical advertising for years and years. In fact, the link between low serotonin and depression goes back to the 1960s.[13]

To correct this chemical imbalance, selective-serotonin reuptake inhibitors (SSRIs) are commonly prescribed. However, many are now considering ssri alternatives that focus on other neurotransmitters.

However, a growing body of evidence disputes the low serotonin-depression link and more attention is being paid to other neurotransmitters that could help those suffering with depression, namely norepinephrine and/or dopamine.[17,18]

Recent research published in Cognitive, Affective, & Behavioral Neuroscience finds that dopamine modulation could repair motivational deficits elicited by stress.[18]

New large-scale review encompassing existing meta-analyses and systematic reviews from University College London concluded that:

"that the huge research effort based on the serotonin hypothesis has not produced convincing evidence of a biochemical basis to depression."[14]

The team of researchers believe these findings are critically important as other research indicates that as many as 85-90% of the public believes that depression is caused by low serotonin or a chemical imbalance.

Interestingly, during the course of their analysis, the team found evidence that individuals who used antidepressants actually had lower levels of serotonin in their blood!

This led them to conclude that long-term antidepressants may actually reduce serotonin concentrations.

The reason for why this happens, according to the researchers, is that the boost in serotonin from antidepressants is short term and may lead to compensatory changes in the brain that produce the opposite effect in the long term.

Lead researcher on the landmark paper, Joanna Moncrieff, noted[15]:

"Our view is that patients should not be told that depression is caused by low serotonin or by a chemical imbalance, and they should not be led to believe that antidepressants work by targeting these unproven abnormalities. We do not understand what antidepressants are doing to the brain exactly, and giving people this sort of misinformation prevents them from making an informed decision about whether to take antidepressants or not."

Something else to consider is that SSRIs come with a laundry list of adverse effects, including[16]:

  • Nausea
  • Insomnia
  • Anxiety
  • Agitation
  • Weight gain
  • Sexual dysfunction

Takeaway

As we've discussed above and in previous articles, taking pharmaceuticals that artificially inflate various neurotransmitters isn't sustainable over the long-term. They may improve things transiently, but at the end of the day there are adverse effects.

DopaRush® and Dopa Rush Shots offer a natural alternative and contain caffeine and tyrosine, that provides the key building blocks needed to support dopamine and norepinephrine.†
