Understanding Alzheimer’s Disease – Signs and Prevention

Understanding Alzheimer’s Disease – Signs and Prevention

What is Alzheimer’s Disease?

A progressive, irreversible brain disorder, Alzheimer’s is the most common cause of Dementia – a syndrome that influences mental cognitive abilities like, reasoning, behavioural, and thinking. It affects a person’s capability to function independently, slows down memory and the ability to perform simple tasks. The onset of Alzheimer’s is marked by a degeneration of brain cells and difficulty in recalling recent events.

What is the difference between Alzheimer’s and Dementia?

Dementia is the broader umbrella under which Alzheimer’s falls.


Dementia is a syndrome or a host of symptoms that hamper independent daily cognitive functions like reasoning and memory. With no absolute diagnosis, it affects the functioning of neurons responsible for transferring messages from the brain to the organs and back. There are several conditions that lead to Dementia, like Alzheimer’s disease and Vascular Dementia.

Common causes of Dementia are said to be –


  • Infections like HIV
  • Vascular diseases
  • Depression
  • Stroke
  • Extreme drug usage


We can even say that Dementia is the next stage of Alzheimer’s and 50-75% of times Alzheimer’s has been seen to progress into Dementia, especially, in older adults.

The symptoms of Alzheimer’s can be controlled whereas Dementia is fatal and the research for diagnosis continues.

What are the warning signs or Alzheimer’s Disease symptoms?

The most prominent symptom of Alzheimer’s is memory loss, and as it advances the condition of the brain degrades (Severe Alzheimer’s). Let’s look at some of the common symptoms that may indicate Alzheimer’s.

Mild Alzheimer’s – the person may seem to be relatively healthy but has difficulty making sense of the world around.


  • Elevated anxiety, personality, and mood issues
  • Memory loss and inability to recognize familiar places
  • Repeating questions and poor decision-making skills
  • Trouble dealing with numbers, like handling money and paying bills


Moderate Alzheimer’s –This is an alarming progression, and includes symptoms like


  • Inability to comprehend language and words – reading and writing impairment
  • Increased illogical thinking
  • Delusions, paranoia, and hallucinations
  • Agitation, anxiety, and restlessness
  • Muscle twitches and inability to multitask
  • Reduced attention span


Severe Alzheimer’s – Majorly characterized by a person’s inability to perform any task by themselves.


  • Skin infections
  • Seizures
  • Loss of bladder control and bowel
  • Weight loss
  • nability to swallow food


How does Alzheimer’s affect the brain?

Alzheimer’s affects the ability of the neurons to communicate with the organs and vice-versa. This miscommunication leads to all the dysfunctionalities that develop into Dementia. The major factors that affect the brain are amyloid plaques and neurofibrillary tangles – don’t be afraid of the fancy names, let’s understand both –

Plaques or Amyloid plaques – they are toxic protein clumps that stick in between two neurons and interfere with the normal cell functioning.

Tangles or Neurofibrillary tangles – The abnormal accumulation of a protein called ‘tau’ inside the neurons leads to the formation of neurofibrillary tangles. Usually, tau helps guide the transfer of nutrients in the neurons. However, in Alzheimer’s the disturbed chemicals detach tau from neurons and entwine to form tangles.

As the level of plaque increases, tau spreads in the brain region responsible for memory. This complicated interaction is responsible for all the brain changes in the Alzheimer’s disease.

Breakthroughs in Alzheimer’s Research

The Alzheimer’s Big Bang – Research led by scientists at the UT Southwestern University have related the onset of Dementia with the toxic tau protein formation – opening new gates for treatment before significant symptoms takeover.

Artificial Intelligence and Alzheimer’s Diagnosis – The researchers at Stanford University have proposed the usage of a 3D Convolutional Neural Networks to get test results from MRI data samples. This is expected to diagnose Alzheimer’s with an accuracy of 94.1 %.

Detecting Alzheimer’s with eye scan – Duke University’s researchers suggest using eye-scanning as a viable source for increasing the detection of Alzheimer’s in patients.

Antidepressants can delay the progression of Alzheimer’s – The antidepressant, selective serotonin reuptake inhibitor (SSRI) can delay the growth of amyloid plaques in the brain; according to the researchers at the University of Waterloo. Though the study is progressing, it promises further direction for Alzheimer’s treatment.

What can be done to prevent Alzheimer’s?

In the absence of any proven diagnostics yet, it’s believed that 99% times, AD symptoms are closely associated with brain inflammation, vascular function, and lifestyle choices. Taking care of these three factors is recommended Alzheimer's disease treatment:

  • Exercise
  • Get good sleep
  • Follow a balanced diet
  • Learn new things
  • Avoid smoking
  • Reduce alcohol intake

More than 50 million people are living with Dementia around the world, as of 2018 – about 33 million of these have Alzheimer’s. With a new case being reported every three seconds, the world’s worried and investing in a wealth of research and technology to understand the reasons and cure for Alzheimer’s in the hope to find a way around it.
