Alzheimer’s Disease: Symptoms, Causes, Risk Factors, Treatment and Diet

Alzheimer’s disease is a brain disorder that gradually destroys memory and thinking skills. The neurodegenerative disorder usually starts with short-term memory loss and ends in the death of brain cells.

The disease is characterized by plaques and tangles in the brain tissue. It is also associated with depression, anxiety, aggression, delusions, and personality changes. It can lead to dementia which means that a person has trouble doing simple tasks such as remembering recent events or following conversations.

Alzheimer’s disease is a progressive, degenerative disease that affects the brain. It is characterized by loss of memory and other intellectual abilities, eventually leading to death.

The two main types of Alzheimer’s are:

  1. Early-onset Alzheimer’s disease
  2. Late-onset Alzheimer’s disease

Early onset Alzheimer’s typically begins before the age of 65 and late onset after 65. The main difference between early and late onset is when the symptoms start to show up. Early onset starts with memory problems while late onset usually starts with more physical problems like clumsiness or mood changes.

There are five stages of Alzheimer’s disease:

  1. Preclinical Alzheimer’s Disease
  2. Mild Cognitive Impairment
  3. Mild Alzheimer’s Disease
  4. Moderate Alzheimer’s Disease
  5. Severe Alzheimer’s Disease

What are the early signs?

The early signs of Alzheimer’s disease are very subtle and often go unnoticed. It is important to know these signs so that you can start taking steps to reduce your risk of developing the disease.

These are the early signs of Alzheimer’s disease:

  • Memory loss
  • Difficulty in performing tasks
  • Confused thinking
  • Difficulty in understanding what is said or written

What are the symptoms of Alzheimer’s disease?

Alzheimers disease is a chronic and progressive brain disorder. It is characterized by loss of memory and mental abilities, disorientation, and personality changes. At first, a person with Alzheimer’s disease are having difficulty in remembering things and old conversions etc.

The symptoms are often difficult to identify at first but they can be observed in the following ways:

  • Difficulty remembering new information
  • Difficulty recalling words
  • Problems with language or understanding speech – Problems with reading comprehension
  • Misplacing items or forgetting where one has placed them
  • Poor judgment or decision making skills.

Brain changes associated with Alzheimer’s disease lead to growing trouble with:

Alzheimer’s disease is a progressive, degenerative disease that affects the brain. It leads to growing trouble with memory and language, and eventually death.

There are many changes in the brain associated with Alzheimer’s disease:

  • Brain cells that make up the hippocampus start to die off
  • The levels of certain neurotransmitters decrease, such as acetylcholine and glutamate
  • There is an increase in beta amyloid plaques which can form between nerve cells
  • The levels of certain proteins rise, such as tau protein


Alzheimer’s disease is a progressive neurodegenerative disease that causes dementia.

The causes of Alzheimer’s disease are not fully understood, but it is believed to be the result of a complex set of factors. These factors include genetics, lifestyle, and environmental and socioeconomic factors.

What are the risk factors of Alzheimer’s disease?

Alzheimer’s disease is a progressive brain disorder that gradually destroys memory and thinking skills.

The risk factors for Alzheimer’s disease include: age, family history, genetics, health conditions, lifestyle choices, and education.


Alzheimer’s disease is a type of dementia that can cause problems with thinking, memory, and behavior. It usually progresses slowly but steadily. Alzheimer’s disease is the most common cause of dementia among older people.

The number of people age 65 and older with Alzheimer’s disease in the United States is projected to increase from 5 million in 2014 to 14 million by 2050. This increase will be due mostly to the aging baby boom generation entering this age group.

Family history and genetics

This section will explore the role that genetics and family history play in the development of Alzheimer’s Disease. While there is no cure for Alzheimer’s Disease, understanding how genes and environmental factors contribute to its onset can help those with the disease better manage their symptoms.

Down syndrome

Down syndrome is a genetic disorder that causes intellectual disability and other developmental delays.

Alzheimer’s is a neurodegenerative disease that leads to dementia, memory loss, and behavioral changes. Down syndrome with Alzheimer’s is the combination of both diseases in one person.

Down syndrome with Alzheimer’s can be challenging because it has an increased risk of developing dementia, which makes it harder for the person to maintain their independence.

The caregiver will need to ensure safety precautions are taken at all times because the person with down syndrome may not be able to remember how to perform tasks like cooking or driving a car..

Mild cognitive impairment

Mild cognitive impairment with alzheimers is a type of dementia that affects language, memory and other thinking skills.


  • Memory problems
  • Language problems (difficulty remembering words)
  • Difficulty following conversations or jokes – Poor judgment
  • Problems with abstractions (such as math)

Lifestyle and heart health

Alzheimer’s is a progressive brain disorder that slowly destroys memory and thinking skills. It is one of the most common form of dementia.

Alzheimer’s disease is the most common form of dementia, but it can be prevented or delayed with lifestyle changes and heart health.

As we age, our risk for developing Alzheimer’s disease increases. There are two main types: early-onset Alzheimer’s Disease (EOAD), which affects people who are younger than 65 years old, and late-onset Alzheimer’s Disease (LOAD), which affects people over 65 years old.

The National Institutes of Health recommends healthy lifestyle choices to reduce your risk for developing Alzheimer’s disease:

  • Exercise regularly
  • Stay social
  • Eat a healthy diet
  • Keep your mind


The effect of Alzheimer’s disease on gender is not yet well understood but it is important to note that Alzheimer’s disease affects women and men differently.

Alzheimer’s disease has a different effect on men and women. Women are more likely to develop the early-onset form of the disease, which usually starts before age 65. Men are more likely to have late-onset AD, which usually starts after age 65.

But, comparatively women live longer than men with alzheimer’s disease.

Poor sleep patterns

Research has shown that people with Alzheimer’s disease have a disrupted sleep pattern. The reasons for this are not yet understood, but the effects are clear.

People with Alzheimer’s disease often experience sleep deprivation because they can’t remember to go to bed or wake up at the right time. They may also experience insomnia because they find it difficult to fall asleep or stay asleep for long periods of time.

People with Alzheimer’s disease may also experience daytime sleepiness and suffer from fatigue as a result of their disrupted sleep cycle. This leads to problems with concentration and attention span, which can make it difficult for them to complete tasks at work, take care of themselves at home, and participate in social activities.


There are many ways to help prevent Alzheimer’s disease from developing in one’s lifetime. Change in diet, exercise and habits are the steps to reduce the risk of cardiovascular disease and some disorders occurs due to Alzheimer’s disease.

Some doctors recommend following tips to reduce Alzheimer’s disease. regular exercise, eating a healthy diet with less sugar and more vegetables, not smoking cigarettes. All these changes may helps with the prevention of Alzheimer’s disease.

  • Regular exercise.
  • Quit smoking and drinking.
  • Eating healthy oils, fresh vegetables,
  • Following Mediterranean diet.
  • All these help to control diabetes, high blood pressure and high cholesterol levels.


Alzheimer’s disease is a progressive, irreversible brain disorder that slowly destroys memory and thinking skills. It is the most common cause of dementia among older people.

There is no cure for Alzheimer’s disease, but treatments can help manage symptoms. The goal of treatment is to maintain function for as long as possible.

Medications can temporarily slow down or stop the worsening of Alzheimer’s symptoms by targeting the symptoms themselves or by preventing additional brain cell death. They may also help with behavioral problems that can be caused by Alzheimer’s disease.

The following are some medications used to treat Alzheimer’s: Aricept (donepezil), Exelon (rivastigmine), Namenda (memantine), Reminyl (galantamine).


Alzheimer’s disease is an age-related neurodegenerative disorder and the most common type of dementia. It is characterized by a gradual loss of memory and other intellectual abilities, as well as emotional changes.

There are some foods that can help reduce the risk of developing Alzheimer’s disease or slow its progression. These include:

  • Green leafy vegetables, such as spinach, kale, collard greens and broccoli
  • Fish rich in omega-3 fatty acids
  • Foods high in vitamin E
  • Foods high in B vitamins

Bottom Line

Alzheimer’s disease is a type of dementia that leads to memory loss. It is the most common form of dementia in adults and is also the most common cause of dementia in people under 65.

Alzheimer’s disease starts gradually, with short-term memory loss and problems with language or numbers. It gets worse over time, leading to a loss of long-term memory that affects daily life. Alzheimer’s disease can also lead to mood swings, personality changes, and difficulty speaking or swallowing.

Alzheimer’s disease are associated with participating in social events, reading, dancing, playing board games, creating art, playing an instrument, and other activities that require mental and social engagement.
