This blog delves into these developments, providing valuable insights for those considering medical marijuana for Alzheimer’s Disease management.

Understanding Alzheimer’s Disease

What Is Alzheimer’s Disease?

Alzheimer’s disease is a neurodegenerative disorder characterized by irreversible neuronal loss, primarily caused by the accumulation of tau proteins and neurofibrillary tangles in the brain tissue. This leads to progressive dementia and memory loss, affecting various cognitive functions such as communication, language, memory, and motor skills. Alzheimer’s significantly impacts a person’s ability to interact with their environment and carry out daily activities, eventually leading to complete dependence on caregivers.

Who Is Affected by Alzheimer’s Disease?

Alzheimer’s Disease predominantly affects older adults, with the risk increasing significantly with age. It’s estimated that 6.7 million Americans aged 65 and older are living with Alzheimer’s dementia, making it one of the most common causes of dementia and a leading cause of disability and dependence among the elderly. Alzheimer’s disease accounts for 60% to 70% of dementia cases. A combination of genetic and environmental factors contributes to the risk of developing Alzheimer’s.

For instance, having a family history of Alzheimer’s increases the risk significantly, while lifestyle factors like smoking can also contribute to its development. In the United States, the prevalence of Alzheimer’s disease varies by state, with larger states like California, Florida, and New York having higher numbers of affected individuals​​​​​​.

Why Does Alzheimer’s Disease Occur?

The onset of Alzheimer’s Disease (AD) is a complex process influenced by various factors, including genetics and molecular mechanisms. A key genetic risk factor identified is apoE4, a variant of apolipoprotein E. Additionally, recent studies have highlighted the role of proteins such as beta-amyloid and tau in the disease’s development. The accumulation of amyloid-β oligomers and neuroinflammation are crucial aspects of AD’s molecular landscape. Researchers have found that the reduced binding of apoE4 to complement factor H can promote amyloid-β oligomerization and neuroinflammation, contributing to the onset of Alzheimer’s disease​​​​​​​​​​.

Furthermore, altered brain energy metabolism related to astrocytes and the degeneration of microglia, immune cells in the brain, have been identified as contributing factors to the disease’s progression. This degeneration appears to be linked to cognitive decline in Alzheimer’s and vascular dementia, possibly initiated by repeated episodes of low blood flow and oxygen delivery to the brain over time due to acute stroke or chronic conditions such as hypertension and diabetes​​​​.

How Does Alzheimer’s Disease Impact Cognitive Functioning?

Alzheimer’s Disease primarily affects cognitive functioning, leading to a gradual decline in memory, reasoning, learning, and thinking abilities. This decline results from the damage and death of nerve cells in the brain, caused by the tangling of tau proteins and the clumping of beta-amyloid proteins.

These processes lead to the formation of plaques that block cell-to-cell signaling and trigger an immune response, causing inflammation. Most people with Alzheimer’s disease are over 65 years old, but the brain changes associated with the disease can begin decades before symptoms are evident​​.
