Exploring the Fermentation-Driven Functionalities of Lactobacillaceae-Originated Probiotics in Preventive Measures of Alzheimer’s Disease: A Review

Alzheimer’s disease (AD) is an ascending, neurodegenerative disorder that attacks the brain’s nerve cells, i.e., neurons, resulting in loss of memory, language skills, and thinking and behavioural changes. It is one of the most common causes of dementia, a group of disorders that is marked by the decline of cognitive functioning. Probiotics are living microorganisms that are beneficial for human well-being. They help in balancing the extent of bacteria in the gut and support the defensive immune system of the body. Studies have found that probiotics can help with a variety of conditions, including mental health. Probiotics are beneficial bacteria that can help to maintain and strengthen a healthy gut microbiome. The gut microbiome is important for healthy brain function, as it is linked to the production of neurotransmitters and hormones that regulate mood and behaviour. This review article includes detailed review on the origination of probiotics and its significance in the treatment of AD.
