Alzheimer's Disease: A Progressive Neurodegenerative Disorder

Alzheimer's disease is a progressive, neurodegenerative disorder characterized by the loss of function and death of nerve cells in several areas of the brain, leading to loss of cognitive function such as memory and language [10].

This degenerative process affects multiple regions of the brain, including those responsible for memory, language, and other higher-order functions. As a result, individuals with Alzheimer's disease experience significant impairments in their ability to think, remember, and communicate.

The progressive nature of Alzheimer's disease means that it worsens over time, leading to a decline in cognitive function and ultimately affecting an individual's daily life and activities [10].

Common Signs and Symptoms of Alzheimer's Disease

Alzheimer's disease is a progressive neurological disorder that affects memory, thinking, and behavior. The symptoms can vary from person to person, but here are the common signs and symptoms:

• Memory Loss: One of the most noticeable symptoms of Alzheimer's is memory loss, especially in the early stages. People with Alzheimer's may forget recently learned information, events, or personal history [1].
• Challenges in Planning or Solving Problems: As the disease progresses, people with Alzheimer's may experience difficulty planning or solving problems, which can affect their daily life and activities [2].
• Difficulty Completing Familiar Tasks: People with Alzheimer's may struggle to complete familiar tasks, such as cooking, managing finances, or even simple tasks like using a phone [3].
• Language Problems: Some people with Alzheimer's may experience language difficulties, including trouble finding the right words or following conversations [4].
• Changes in Mood: Changes in mood are also common symptoms of Alzheimer's, including depression, anxiety, and agitation [5].
• Social Withdrawal: As the disease progresses, people with Alzheimer's may withdraw from social interactions and activities they once enjoyed [6].

Early Warning Signs

The early warning signs of Alzheimer's can be subtle, but they can include:

• Forgetting recently learned information or events
• Difficulty completing familiar tasks
• Trouble planning or solving problems
• Changes in mood or behavior

It's essential to note that these symptoms can also be caused by other conditions, and only a medical professional can accurately diagnose Alzheimer's disease.

Diagnostic Tests for Alzheimer's Disease

Alzheimer's disease can be diagnosed using various diagnostic tests, which are essential in confirming the presence of the condition. Here are some of the diagnostic tests used to diagnose Alzheimer's disease:

• Cognitive Assessments: These tests evaluate a person's mental abilities, such as memory or thinking. Most cognitive assessments are designed to identify any decline in cognitive function [8].
• Diagnostic Tests: These include medical history, mental status tests, physical and neurological exams, diagnostic tests, and brain imaging [5].
• Brain Imaging: This includes computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET) scans to support an Alzheimer's diagnosis [3].
• Biomarker Tests: These can measure biological signs of disease in the brain, which can be used with other tools to diagnose Alzheimer's [2].

It is essential to note that there is currently no single diagnostic test that can detect if a person has Alzheimer's disease (AD) [6]. An accurate diagnosis of Alzheimer's disease requires either a sample of cerebrospinal fluid or a brain imaging test called a PET scan [7].

Medication Use for Alzheimer's Disease

According to recent data, there are various medications used to treat Alzheimer's disease. Here are some key points:

• Cholinesterase Inhibitors: These medications, which include donepezil, rivastigmine, and galantamine, can be prescribed for people with early- to mid-stage Alzheimer's disease [8].
• Memantine (Namenda): This is the only drug approved by the FDA to treat symptoms due to moderate to severe stages of AD. It works by reducing the amount of glutamate in the brain [7].
• Leqembi (lecanemab-irmb): This medication, approved in 2023, is a new category of medications for treating Alzheimer's disease. However, its use may be limited to specific patient populations [6].

Medication Use by Demographics

Interestingly, the use of cholinesterase inhibitors varies across different demographics:

• Male vs. Female: Men are more likely to receive cholinesterase inhibitors (70% vs. 37%) compared to women [10].
• Age and Sex: The use of miscellaneous central nervous system agents is higher among females than males, while non-cardioselective beta blockers are more commonly prescribed for men [10].

Other Medications

While not specifically approved for Alzheimer's disease, other medications like tacrine (a first-generation cholinesterase inhibitor) have been studied in the past. However, their use has been limited due to side effects [9].

The differential diagnosis of Alzheimer's disease involves ruling out other potential causes of dementia-like symptoms. Here are some key points to consider:

• Other degenerative dementias: Conditions like Parkinson's disease, Pick's disease, and frontotemporal dementia can have similar symptoms to Alzheimer's disease [3].
• Emotional and metabolic causes: Depression, organ failure, and other metabolic disorders can also present with dementia-like symptoms [4].
• Dementias with prominent motor signs: Conditions such as Lewy body dementia, idiopathic Parkinson's disease, progressive supranuclear palsy, and corticobasal degeneration can be distinguished from Alzheimer's disease by their prominent motor symptoms [5].
• Other conditions that may mimic Alzheimer's disease: These include vascular dementia, mixed dementia, and normal pressure hydrocephalus [1].

To accurately diagnose Alzheimer's disease, healthcare professionals must consider these differential diagnoses and use a range of diagnostic tools, including medical history, physical examination, laboratory tests, and imaging studies.
