Describe Alzheimer’s disease.


A brain ailment that worsens over time is Alzheimer’s disease. It is typified by alterations in the brain that result in protein accumulation. Alzheimer’s disease results in the ultimate death of brain cells and shrinkage of the brain. The most prevalent cause of dementia, which is characterized by a progressive loss of memory, thinking, behavior, and social skills, is Alzheimer’s disease. The way a person functions is impacted by these changes.

In the US, 6.5 million adults 65 years of age and older have Alzheimer’s disease. Over 70% of them are 75 years of age or older. 60% to 70% of the approximately 55 million persons with dementia globally are thought to have Alzheimer’s disease.

The inability to recall recent conversations or occurrences is one of the disease’s early symptoms. It eventually leads to severe memory loss and the inability to carry out daily duties.

Medication may help symptoms get better or slow them down. Services and programs can be used to support individuals with the illness and those who care for them.

Alzheimer’s disease does not have a cure. Severe brain damage at an advanced level might result in infection, starvation, or dehydration. There is a chance of death from these issues.


The primary sign of Alzheimer’s disease is memory loss. Memory loss from recent discussions or experiences is one of the early warning signals. But as the illness worsens, memory deteriorates and new symptoms appear.

An individual suffering from the illness may initially be conscious of difficulties with memory and cognitive function. A friend or family member may be more likely to identify problems if symptoms worsen.

Alzheimer’s disease-related brain abnormalities cause increasing problems with:


While occasional memory loss is common in everyone, Alzheimer’s disease-related memory loss is persistent and worsens with time. Memory loss gradually impairs one’s capacity to operate at home or at work.

Individuals suffering from Alzheimer’s may:

Rephrase questions and comments several times.

Forget meetings, discussions, and activities.

Items are frequently misplaced and placed in odd locations.

Become lost in areas they used to be familiar with.

Names of regular things and family people eventually slip your mind.

struggle to articulate ideas, describe objects, or participate in discussions with the appropriate language.

Reasoning and contemplating

Alzheimer’s disease impairs one’s ability to focus and think clearly, particularly when it comes to abstract ideas like numbers.

Managing many tasks at once is very challenging. Keeping track of funds, balancing checkbooks, and making on-time bill payments may be difficult. A person suffering from Alzheimer’s disease may eventually lose their ability to identify and manipulate numbers.

Forming conclusions and judgments

Decision-making and judgment in daily life become increasingly difficult when one gets Alzheimer’s disease. For instance, a person could dress inappropriately for the weather or make bad decisions in social situations. Someone may find it more difficult to react to common issues. For instance, the person could be incapable of making judgment calls when driving or dealing with food burning on the stove.

Organizing and carrying out routine duties

Simple tasks that need to be completed sequentially become difficult. This may be preparing and preparing a meal or engaging in a beloved activity. Advanced Alzheimer’s patients eventually lose the ability to do simple activities like getting dressed and taking a shower.

Retained abilities

People with Alzheimer’s disease are able to retain certain skills even as their symptoms worsen, despite significant changes to their memory and cognitive abilities. Reading, listening to literature, telling tales, sharing experiences, dancing, singing, sketching, and crafting are examples of preserved talents.

Because these abilities are governed by brain regions that are impaired later in the course of the disease, they could be retained longer.

When to visit a physician

There are several illnesses that might cause memory loss or other symptoms of dementia. A few of such ailments are treatable. See a healthcare provider if you have concerns about your memory or other cognitive abilities.

Discuss your worries and inquire about visiting a health care provider jointly if you are worried about the cognitive abilities you see in a friend or family member.
