Unusual Alzheimer’s Symptoms

Alzheimer’s is a progressive brain disorder affecting memory, thinking, and behaviour. It is the most common cause of dementia in older adults. While memory loss is the most well-known Alzheimer’s symptom, several other unusual symptoms can occur. This article will explore some of the early and unusual symptoms of Alzheimer’s.

Early Alzheimer’s Symptoms

In the early stages of Alzheimer’s, a person may experience mild cognitive impairment characterized by memory problems more significant than regular age-related changes. This may include forgetting recent events or conversations, misplacing items, or needing help making decisions. However, these early symptoms can be subtle and may not be noticeable initially.

Another early Alzheimer’s symptom is difficulty with language. This can manifest as trouble finding the right words, repeating phrases, or needing help to follow conversations. This can be particularly frustrating for individuals who have always been articulate and have had no trouble communicating.

Additionally, changes in mood or personality can be an early sign of Alzheimer’s. A person may become apathetic, withdrawn, or experience unexplained changes in their behaviour. They may also become irritable, anxious, or depressed, which can be attributed to changes in the brain caused by the disease.

Unusual Symptoms of Alzheimer’s

As Alzheimer’s progresses, a person may experience more unusual symptoms. For example, some individuals may develop visual or spatial difficulties, such as difficulty judging distances or recognizing colours. This can make navigating familiar environments challenging or completing tasks requiring coordination, such as driving. Below are unusual symptoms of Alzheimer’s:


Another unusual Alzheimer’s symptom is a condition known as aphasia. This is a language disorder that affects a person’s ability to communicate. It can manifest in several ways, including difficulty speaking, understanding language, reading, or writing. In some cases, a person with aphasia may have trouble expressing themselves verbally, while in other cases, they may struggle to understand what others are saying.

Agitation and Aggression

Agitation and aggression can also be unusual symptoms of Alzheimer’s. A person may become agitated or irritated and lash at others verbally or physically. This can be particularly challenging for caregivers, as it can be difficult to predict when these outbursts will occur.

Sleep Problems

Another unusual symptom of Alzheimer’s is sleep disturbances. A person may have trouble falling or staying asleep and become restless during the night. They may also experience daytime drowsiness, making it difficult to stay awake or concentrate during the day.


Delusions and hallucinations can also occur in individuals with Alzheimer’s. This can manifest as believing in something that is not true or experiencing sensory perceptions that are not real. For example, a person may believe someone is stealing from them, even if no evidence supports this claim. Alternatively, they may see or hear things that are not there, such as a person or an animal in the room.

Finally, a person with Alzheimer’s may experience changes in their sense of taste or smell. This can make it challenging to enjoy food, as they may find that certain flavours or textures need to be more appealing. In some cases, they may even experience a loss of appetite, leading to weight loss and malnutrition.

Diagnosis and Treatment of Alzheimer’s

If you or a loved one are experiencing these symptoms, seeing a healthcare professional for a diagnosis is essential. While there is no cure for Alzheimer’s, treatments are available that can help manage symptoms and improve quality of life.

One standard treatment for Alzheimer’s is medication. In addition to medication, several non-pharmacological treatments can help manage symptoms of Alzheimer’s. For example, occupational therapy can help individuals with Alzheimer’s learn new strategies for managing daily activities and maintaining independence. Speech therapy can also be helpful for individuals with language or communication difficulties.

Another important aspect of Alzheimer’s treatment is support for caregivers. Caring for a loved one with Alzheimer’s can be challenging and stressful, and caregivers must have access to resources and support. This may include counselling, support groups, or respite care services.

Finally, maintaining a healthy lifestyle can also help manage symptoms of Alzheimer’s. This may include regular exercise, a healthy diet, and getting enough sleep. Engaging in social activities and hobbies can also be beneficial, as it can help stimulate the brain and improve mood.


It’s important to note that while some of these symptoms may indicate Alzheimer’s, they could also be caused by various other conditions. It’s best to consult with a medical professional to determine the root cause of the symptoms and develop an appropriate treatment plan.

Final Words

Alzheimer’s is a progressive brain disorder affecting memory, thinking, and behaviour. While memory loss is the most well-known symptom of Alzheimer’s, several other unusual symptoms can occur. Early Alzheimer’s symptoms may include difficulty with language, changes in mood or personality, and mild cognitive impairment. As the disease progresses, individuals may experience more unusual symptoms such as visual or spatial difficulties, language disorders, and sleep disturbances.

While there is no cure for Alzheimer’s, treatments are available that can help manage symptoms and improve quality of life. This may include medication, non-pharmacological treatments such as occupational or speech therapy, caregiver support, and a healthy lifestyle. If you or a loved one are experiencing Alzheimer’s symptoms, it is crucial to see a healthcare professional for a diagnosis and to explore treatment options.

Interesting, but all these unusual symptoms could result from other conditions. How many of these symptoms would indicate Alzheimer’s?

I read a post on Instagram about how much a person walking can reveal the likelihood of developing Alzheimer’s. It wasn’t so reliable, but has there been any research?
