Thyroid, kidney, liver, heart and lung problems, urinary and chest infections and strokes are among the many medical conditions that can produce dementia-like symptoms.
Introduction: The five-word test (5WT) is a serial verbal memory test with semantic cuing. It is proposed to rapidly evaluate memory of aging people and has previously shown its sensitivity and its specificity in identifying patients with AD.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
Pseudodementia is a condition that appears similar to dementia but does not have its root in neurological degeneration. Some people call the condition depressive pseudodementia, as the symptoms often stem from mood-related conditions such as depression.
Depression is often mistaken for dementia and may appear before dementia develops. As well as low mood and poor self-care, older people may be disorientated and have memory loss. Generalised anxiety disorder is extreme and long-lasting anxiety.
People with frontotemporal dementia (FTD) are often misdiagnosed with Alzheimer's disease (AD), psychiatric disorders, vascular dementia or Parkinson's disease. The early symptoms and the brain image are often the most helpful tools to reach the right diagnosis.
Alzheimer's disease
The causes of Alzheimer's are not entirely clear, but healthcare professionals find clumps of a protein called beta-amyloid in the brains of people with this disease. Alzheimer's often develops gradually and may be the slowest of all types to progress.
Creutzfeldt-Jakob disease causes a type of dementia that gets worse unusually fast. More common causes of dementia, such as Alzheimer's, dementia with Lewy bodies and frontotemporal dementia, typically progress more slowly. Through a process scientists don't yet understand, misfolded prion protein destroys brain cells.
Many other conditions, in addition to the ones above, can cause symptoms that mimic dementia or Alzheimer's disease, including disorders of the heart, lungs, liver or kidneys, thyroid problems, sodium or vitamin B12 deficiency, some cancers, pain, constipation, heavy alcohol use and depression.
The five-minute cognitive test (FCT) was designed to capture deficits in five domains of cognitive abilities, including episodic memory, language fluency, time orientation, visuospatial function, and executive function.
The main sign of mild cognitive impairment is a slight decline in mental abilities. Examples include: Memory loss: You may forget recent events or repeat the same questions and stories. You may occasionally forget the names of friends and family members or forget appointments or planned events.
The Montreal Cognitive Assessment (MoCA) is a tool that helps healthcare professionals detect mild cognitive impairment and Alzheimer's disease in people. A 2021 study found that it is a better measure of cognitive function than the MMSE. It consists of 30 questions that take 10–12 minutes to accomplish.
The SAGE test is a 12-question exam that measures cognitive functioning and may help a physician determine whether Alzheimer's is present.
The Self-Administered Gerocognitive Exam, known as SAGE, is a brief, pen-and-paper cognitive assessment tool designed to detect the early signs of cognitive, memory, or thinking impairments. The test evaluates your thinking abilities. This can help your doctors understand how well your brain is functioning.
Most cases of sudden confusion and rapidly progressive dementia in an elderly person are due to delirium caused by infection. Urinary infections and pneumonia can trigger acute confusion that comes on quickly, causing people to be incoherent, muddled and disorientated.
other long-term health problems – dementia tends to progress more quickly if the person is living with other conditions, such as heart disease, diabetes or high blood pressure, particularly if these are not well-managed.
Dementia Doesn't Always Mean Alzheimer's
Your memory also can be harmed by many other health issues, such as a stroke, Parkinson's disease, or a buildup of fluid on your brain. If you notice symptoms that have you concerned, see a doctor right away.
People with dementia often rely on their routines as a source of comfort. A daily routine helps a person know what to expect. This means that a sudden disruption in routine may cause dementia symptoms to get worse. This is especially true if a person experiences stress.
Mild cognitive impairment (MCI) is the stage between the expected decline in memory and thinking that happens with age and the more serious decline of dementia. MCI may include problems with memory, language or judgment. People with MCI may be aware that their memory or mental function has "slipped."
People with dementia, especially those in the later stages, can often spend a lot of time sleeping.
In the earlier stages, memory loss and confusion may be mild. The person with dementia may be aware of — and frustrated by — the changes taking place, such as difficulty recalling recent events, making decisions or processing what was said by others. In the later stages, memory loss becomes far more severe.
Alzheimer's disease progressively destroys brain cells over time, so during the early stages of dementia, many do recognize something is wrong, but not everyone is aware. They may know they are supposed to recognize you, but they can't.
Fear of causing emotional distress in their patients and the lack of time and resources to fully explain what the diagnosis means. This was true of both primary care doctors as well as neurology specialists who have more expertise in brain-related disorders.
