Alzheimer’s Disease: Symptoms, Causes, and treatment

Alzheimer’s, a type of dementia, affects memory, thinking and behavior. Oftentimes the effects of Alzheimer’s can influence daily tasks. It alone accounts for 60-80% of all dementia cases. It’s a common misconception that Alzheimer’s is a normal part of aging, those who are older are at a higher risk, but nearly 200,000 Americans under the age of 65 have been reported to have Alzheimer’s.

Alzheimer’s is often a slowly progressive disease, so it’s indeed more difficult to spot definitive symptoms. According to Mayo Clinic, some of the symptoms of Alzheimer’s include: repeating statements, forgetting conversations, getting lost in familiar places, forgetting names of family members, difficulty concentrating, inability to make a judgment. The effects of Alzheimer’s on the brain can also affect moods and behaviours such as depression, apathy, mood swings, and wandering. Alzheimer’s can still be treated, so it’s important to get treatment as soon as possible.  


To diagnose the severity of Alzheimer’s doctors run multiple types of tests. They will most probably do a physical and neurological exam by testing: reflexes, muscle tone, coordination, balance, sense of sight and hearing, etc. Doctors are likely to do an MRI scan or a CT scan to produce detailed images of brian.  


While the exact cause of Alzheimer’s isn’t fully understood, the idea is that the brain proteins tend to fail to function properly, which then disrupts the work of neurons. When neurons are damaged, they eventually lose connections and die. In many ways, Alzheimer’s is connected to a combination of genetic, lifestyle, and environmental factors. 


There are two types of drugs that are currently used to help with Alzheimer’s:

Cholinesterase Inhibitors – Cholinesterase inhibitors aim to increase communication between the nerve cells to improve the symptoms of Alzheimer’s.  

Memantine – Decreases the abnormal brain activity, it also improves the ability to think and slows down the loss of abilities for people who are diagnosed with Alzheimer’s disease. 

In conclusion, Alzheimer’s disease is a common yet disheartening disease that affects a living body of people across the world. Although there aren’t direct solutions, treatment can improve it. Make sure to contact your local doctor if the symptoms seen above persist.
