Alcohol And Alzheimer's
There have been numerous studies that state that alcohol consumption may have a complex relationship with Alzheimer’s disease (AD). Though it is believed that drinking alcohol in moderation provides a protective effect, abusing it reduces one’s cognition and increases the risk of AD.
Some studies have shown that excessive drinking may increase amyloid-β (Aβ) production, which is the marker for AD. There have been some studies that state that alcohol may disrupt tau protein metabolism, which is known to cause neurofibrillary tangles. This is seen in some animal studies where chronic alcohol consumption aggravates brain atrophy and increases Aβ plaque disposition. Some human studies have shown a relationship between alcohol consumption and the risk of getting AD. However, it is believed that light or moderate drinking does not reduce the risk of AD. (Finder & Glockshuber., 2007)
Does Alcohol Increase The Risk Of Alzheimer's?
- Correlation: Some studies have stated that those who drank in moderation, around 1 to 2 drinks a day had a lower risk of developing AD. However, those who were heavy drinks have shown an increased risk of AD. However, it is believed that there may be other factors that are linked to this.
- Causation: Some studies indicate that alcohol may have neuroprotective effects, which aid in reducing signs of AD. However, some research states that this is because moderate drinking does not affect the person due to their healthy lifestyle, such as social engagement, nutrition, and physical activities for dementia patients. (Heyman et al., 2016)
Findings And Studies On Alcohol Increasing The Risk Of Alzheimer’s
- Alcohol levels may injure the liver, thus increasing the rate of AD.
- Aβ aggregation and tau phosphorylation are heightened.
- Impairment towards cognition and memory
- Alcohol may reach genetic threads such as the APOE ε4 allele which may increase the risk of AD.
- Genetic factors also play a role in this, as they may affect metabolism and brain function.
How Does Alcohol Affect Alzheimer's Disease Progression?
- Alter the human genome as ethanol, which is an alcohol component, can change one’s gene. This could potentially alter the brain’s function and its structure, causing it to contract AD.
- Hasten the rate of cognition in patients with AD. This shows that alcohol causes the progression of diseases and, in the long run, causes permanent damage to the brain.
Studies have shown that moderate to heavy consumption of alcohol increases the risk of AD. However, an epidemiology study states otherwise that moderate and heavy usage of alcohol had no effect or risks of AD. The association between AD and alcohol is that heavy usage and consumption of hard liquor speed up cognitive decline in AD patients. Thus, it is important to know how to help someone with cognitive impairment. (Rehm et al., 2003)
Therefore, one must reduce the consumption of heavy drinking as a means to prevent AD. This is because there may be a correlation between the usage of alcohol and AD. However, it is believed that more tests need to be conducted to understand the mechanisms between alcohol and the progression of AD.
Overall, the mechanisms behind the consumption of alcohol may vary, as some research states that moderate drinking may have antioxidant benefits, whereas excessive drinking may increase oxidative stress and inflammation. Moreover, moderate drinking may enhance brain glucose metabolism and excessive consumption affects glucose metabolism. To add on, the accumulation of amyloid-β is said to increase with excessive usage and decrease with moderate usage.

Can Drinking Cause Alzheimer's Or Other Dementias?
There is no straightforward answer when it comes to alcohol consumption and its relationship with Alzheimer’s and other types of dementia. This is because it is believed to be complex and there have been studies that indicated that moderate drinking may lower the risk of AD while heavy drinking increases cognitive decline and the rate of dementia.
Thus, in the long run, one may develop alcohol-related dementia (ARBD), which is a type of dementia. This is due to excessive drinking and causes memory loss, reduction in attention, and being unable to solve problems. However, ARBD may be reversed if one stops drinking, seeks proper treatment, and switches to a healthy and well-balanced diet. Though there are certain similarities between AD and ARBD, ARBD is more often reversible, whereas AD is a neurodegenerative disorder due to the accumulation of beta-amyloid plaques and tau tangles in the brain.
What Are The Effects Of Alcohol On Alzheimer's Patients?
The effects of alcohol consumption on Alzheimer’s patients are looked upon in terms of moderate and heavy consumption. Those who moderately drink around 1–2 drinks per day may have a protective edge over Alzheimer’s Disease (AD), whereas excessive consumption, which is more than 2 glasses per day, may increase amyloid plaques, and brain atrophy, and worsen cognitive decline.
It exacerbates the symptoms by worsening the progression of AD, causing irritation and aggression, and disrupting sleep in AD patients. Moreover, if one is on medications such as cholinesterase inhibitors, antipsychotics, and other medications, it may increase the risk of AD, worsen its side effects such as nausea and vomiting, and cause other adverse effects.
Therefore, it is highly recommended that AD patients do not drink excessively, be closely monitored by their loved ones and healthcare professionals, and seek the assistance of healthcare professionals to either change their medication or advise on the best lifestyle.

- Excessive alcohol abuse may increase the risk of dementia and Alzheimer’s disease (AD).
- Consuming alcohol in moderation with 1–2 drinks a day may protect against AD.
- Abusing alcohol in the long run may cause permanent brain damage. Thus, it is important to conduct brain exercises to prevent Alzheimer’s.
- Trigger neuroinflammation
- Accelerate neurodegeneration and aggravate microglial activation, which causes the disease to progress.
What Is Alcohol-Related Dementia And How Is It Different From Alzheimer's?
Alcohol-related dementia is caused by abuse of alcohol in the long run, whereas Alzheimer’s is a neurological issue that impairs cognition. ARD is most times reversible compared to Alzheimer’s, where it causes deterioration of thinking capacity, memory, and overall health. ARD takes place due to the damage in an individual’s frontal load, which causes short-term memory loss. However, Alzheimer’s is a slow decline in language, memory, and problem-solving skills that is caused by the increase in beta-amyloid plaques and neurofibrillary tangles.
Wernicke-Korsakoff syndrome (WKS) is a branch of ARBD that takes place due to acute brain damage and memory impairment due to chronic alcohol abuse. When someone abuses alcohol, it affects the thiamine level in the brain, causing it to diminish significantly. Patients may suffer from confusion, disorientation, memory impairment, and an inability to process new information.
How Is Alcohol-Related Brain Damage (Arbd) Treated?
The treatment for alcohol-related brain damage (ARBD) varies depending on the intensity of the brain damage. It is important to focus on addressing issues such as addiction, and its symptoms and focus on recovery. There are several types of ARBD, such as WKS, cerebellar disease, Alzheimer’s type dementia, and vascular dementia.
Thus, various therapy options are needed to combat ARBD, such as cognitive behavioral therapy (CBT), antidepressants, antipsychotics, mood stabilizers, vitamin B1, rehabilitation therapy, supportive cases from family, and various types of counseling. The prognosis depends on the types of ARBD and mostly it requires treatment depending on the severity of the damage.
What Are The General Causes And Risk Factors Of Alzheimer's And Dementia?
The general risk factors that cause Alzheimer’s and dementia could be due to neurological conditions, head injuries, strokes, or other types of neurodegenerative diseases. Therefore, it is important to understand the genetic factors that contribute to the risk of Alzheimer’s and dementia. These factors may be due to family history of AD and dementia, the emergence of the APOE gene, inherited genes, old age, gender, where women are more at risk, and ethnic groups such as African Americans and Hispanics are believed to be more prone towards the disease. This should not be a hardcore fact, as lifestyle also plays a factor when it comes to risk factors such as smoking, excessive consumption of alcohol, education, isolation, depression, cholesterol, diabetes, and many more.
Can Alcohol Cause Aphasia Or Other Brain Disorders?
Alcohol may cause aphasia or other types of neurological brain disorders. Aphasia occurs when part of the brain that is responsible for language processing is affected and damaged. This could be potentially due to alcohol abuse, as ethanol can damage the brain, causing oxidative stress, inflammation, which causes tissue damage and disruption of neurotransmitters, which are responsible for the production of GABA and glutamate.
Moreover, alcohol abuse causes thiamine (B1) deficiency in individuals and causes harm to brain health. Thus, it is important to identify this at an early stage and intervene to reverse the effects of thiamine and the progression toward brain disorders.
How Much Alcohol Is Too Much?
Too much alcohol is more than 5 glasses for males and 4 for females on a single occasion. Drinking too much alcohol affects one’s cognitive health and increases the risk of head and neck cancer, esophageal cancer, impaired cognition, neurological and brain atrophy, and the risk of Alzheimer’s and dementia. While it is important to drink in moderation, one will need to determine that drinking standard sizes vary and factors such as metabolism and health conditions play a huge role when it comes to alcohol consumption. It is important to hold your drink and to know when to stop and work towards avoiding alcohol dementia.
