How to Diagnose Alzheimer's Early Onset?
Early Onset Alzheimer’s Disease (EOAD) is diagnosed in individuals aged 65 or younger

Alzheimer’s disease is a devastating illness with no known cure or effective treatment. It is known to affect people of all ages, however, early onset Alzheimer’s typically affects individuals between the ages of 30 and 65. Early diagnosis is crucial for those affected by the illness, as it can help them receive the best treatment and care possible over time. The purpose of this guide is to provide an overview of how to diagnose early onset Alzheimer’s, including its definition, risk factors, signs and symptoms, diagnostic tests and procedures, treatment options, and tips for those diagnosed. By understanding the various aspects of early onset Alzheimer’s, readers will gain valuable insight into how the illness is detected, managed, and treated.

Alzheimer’s is an irreversible and progressive brain disorder which affects memory, thinking and language skills. It is a degenerative disorder, meaning that over time, the effects worsen. Early Onset Alzheimer’s Disease (EOAD) is diagnosed in individuals aged 65 or younger. It is estimated that around 5% of people with Alzheimer’s have early onset; worldwide, this is around 4.6 million people.

Diagnosis of EOAD is more difficult than other forms of Alzheimer’s, as it must be done before the symptoms have started to present themselves. To diagnose EOAD, doctors will look for subtle changes in behaviour and mental functioning, such as memory problems. They may also use laboratory tests, such as blood tests and neurological scans, to rule out other conditions which may be causing the symptoms. If a diagnosis of EOAD is made, specialist treatment can begin.

    Risk Factors for Early Onset Alzheimer’s

    Early onset Alzheimer’s is a form of the degenerative neurological disease that affects people before the age of 65. While it affects a relatively small number of people, it is important to be aware of the factors that increase your risk for early onset Alzheimer's. Knowing what these risk factors are can help you take steps to reduce your chances of developing the illness.


    Age is the biggest risk factor for all forms of Alzheimer’s. Those over 65 are at a greater risk for developing the illness. Although, with early onset Alzheimer’s, those who are under the age of 65 may still be at risk.

    Family History

    Having a family history of Alzheimer’s increases the risk of developing early onset Alzheimer’s. It is important to know if anyone in your family has had the disease as this will increase your risk.


    Certain genetic mutations have been linked to Alzheimer’s. Research suggests that some people may carry certain genes which increase their chances of developing the illness. If you have a parent, sibling, or other close relative with Alzheimer’s, it is important to consult a doctor to discuss genetic testing and other options.

    Environmental Factors

    There are numerous environmental factors which may increase a person’s chances of developing early onset Alzheimer’s. Exposure to certain toxins such as lead and mercury can cause neurological damage and increase one’s risk. Similarly, head injuries, chronic stress, and poor lifestyle choices such as smoking and drinking alcohol can also lead to increased risk of Alzheimer’s.

    Signs and Symptoms of Early Onset Alzheimer’s

    Alzheimer’s is a devastating condition, and identifying it in its early stages is key to managing symptoms and providing care. There are several warning signs that can indicate that someone may be suffering from early onset Alzheimer’s, and understanding these can be incredibly helpful for both the individual and their families.

    The most common symptoms of early onset Alzheimer’s include memory loss, difficulty completing familiar tasks, difficulties with problem-solving or planning, confusion with time or place, difficulty recognising everyday objects, and changes in mood or personality. It’s important to note that these symptoms don’t necessarily indicate early onset Alzheimer’s - they can be due to other diseases and conditions or even natural ageing processes. However, if any of these symptoms occur suddenly or together then it is important to seek medical advice as soon as possible.

    Other signs to look out for include a decrease in judgement or decision-making skills, problems with speech or writing, a lack of interest in activities previously enjoyed, withdrawing from family and friends, and misplacing items and not being able to recall where they were placed.

    Early diagnosis of Alzheimer’s is essential for successful treatment; the earlier it is identified, the more options the individual has in terms of managing the illness. The best way to diagnose Alzheimer’s is through a process of tests and evaluations. It is important to note that although the symptoms can provide an indication of the disease, a full medical evaluation is the only way to diagnose it accurately.

    Diagnostic Tests and Procedures for Early Onset Alzheimer's

    For anyone suspected to be suffering from early onset Alzheimer’s, there are a variety of tests and procedures that can help confirm or deny the diagnosis. This section will discuss the diagnostic tests and procedures available and what they involve.

    Physical Exam and Medical History

    The first step in diagnosing early onset Alzheimer’s is typically a physical exam. During this exam, a doctor will take a medical history and ask questions about any symptoms being experienced. This is to determine if any other illnesses could be causing or contributing to the symptoms, and to rule them out as potential causes.

    Neuropsychological Testing

    After a physical exam and any necessary blood work, patients may be referred for neuropsychological testing. This type of testing consists of various tasks that assess memory, language, thinking, and other cognitive abilities. It is used to measure any cognitive decline that may have taken place, and to determine if it could be linked to Alzheimer’s.

    Brain Imaging Scans

    Brain imaging scans such as Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) scans may also be ordered by doctors to look for changes in the brain that might suggest the presence of Alzheimer’s. These changes can include an overall shrinkage of the brain, as well as decreased activity in certain areas.

    Genetic Tests

    Genetic tests can also be done to look for any genetic mutations that may indicate the presence of early onset Alzheimer’s. However, these tests are not always reliable as mutations related to early onset Alzheimer’s are not present in everyone who has the condition.

    Lumbar Puncture

    In some cases, doctors may order a lumbar puncture, also known as a spinal tap. This procedure involves taking a sample of cerebrospinal fluid (CSF) from the spine in order to diagnose or rule out Alzheimer’s. The CSF will be analyzed for any abnormal proteins that may indicate the presence of the illness.

    These are the most commonly used tests and procedures for diagnosing early onset Alzheimer’s. All of these will help a doctor make an accurate diagnosis and plan an appropriate treatment plan.

    Treatment Options for Early Onset Alzheimer’s

    If you have been diagnosed with early onset Alzheimer’s, there are a number of treatment options available to address your condition. Treatment for Alzheimer’s is focused on managing symptoms and improving quality of life, as there is currently no known cure. While treatment can help, it cannot stop the progression of the disease.

    Drugs like cholinesterase inhibitors and memantine are among the most common treatments, and they work by targeting the chemicals in your brain involved in memory and thinking. While these drugs may help improve memory and other cognitive functions in some cases, they can also come with side effects such as nausea, vomiting, diarrhea, weight loss, and headaches.

    Other treatments include physical, occupational, and speech therapies to help maintain or regain dexterity and independence with daily activities. Social interaction and mental stimulation are also important elements in treating Alzheimer’s, so attending support groups or engaging in activities such as arts and crafts may be beneficial. Finally, approaches such as yoga, tai chi, massage therapy, and aromatherapy can help improve mental clarity and reduce stress.

    The effectiveness of these treatments depends on the individual, so it is important to talk to your doctor to figure out which approach is right for you. It is also important to remain informed about the latest research and advancements in Alzheimer’s treatment, as new discoveries are being made all the time.

    If you have been diagnosed with Early Onset Alzheimer’s, it is important to remember that you are not alone. There are many resources available to help you manage your condition, and to live a full and meaningful life. Here are a few tips on how to cope:
