Current NHS guidelines recommend limiting alcohol intake to a maximum of 14 units per week, underscoring that there is no completely safe level of drinking.

According to the Alzheimer's Society, one in three individuals born in the UK today will develop dementia, primarily due to Alzheimer's disease.

Alzheimer's disease is characterized by memory issues, cognitive decline, and mood changes, which can significantly impact daily life.

Individuals experiencing memory or cognitive decline are advised to consult a health professional, typically their GP, for assessment.

If dementia is suspected, GPs usually refer patients to local memory services for thorough evaluations, where specialists can provide a diagnosis.

The researchers plan to expand their study with larger datasets to further investigate the relationship between alcohol use disorder and Alzheimer's disease.

Pietro Paolo Sanna, the senior author of the study, noted that both alcohol use disorder and Alzheimer's disease exhibit dysregulated cell-type-specific genes and pathways, suggesting a common molecular mechanism.

The Alzheimer Society lists high alcohol consumption among various risk factors that can increase the likelihood of developing Alzheimer's disease.

A new study published in the eNeuro journal reveals that alcohol consumption may accelerate the progression of Alzheimer's disease, which is known for causing memory issues and cognitive decline.

The research indicates that both alcohol use disorder (AUD) and Alzheimer's disease exhibit similar alterations in brain gene expression, particularly affecting inflammation and cellular function.

Analyzing RNA sequencing data from the brains of 75 Alzheimer's patients and 10 non-affected individuals, the study found upregulation of inflammatory genes and disruptions in cell signaling linked to both conditions.

First author Arpita Joshi emphasized the importance of recognizing alcohol use disorder as a significant risk factor for developing Alzheimer's disease.
