Dementia is common in people over the age of 65. However, early onset dementia and associated early onset Alzheimer’s disease is much less common, affecting people in their 40s and 50s.
Signs of early onset dementia include:
- Personality and mood changes
- Increasing confusion
- Forgetting things
- Misplacing items
- Losing track of the date, time, or year
- Language problems, such as difficulty finding the right words
- Disorientation and poor judgement
- Difficulty completing familiar tasks
- Misplacing items
- Loss of sense of smell
What causes early onset dementia?
Although the exact trigger of the disease is unknown, research has shown that damage to the nerve cells may be caused by proteins in the brain:
- Beta-amyloid protein, which forms plaques over the neural tissue and damages memory cells in the brain
- Tau protein, which forms tangles and kills the neurons
Although these plaques and tangles occur in almost all people as they age, people with Alzheimer’s disease develop many more, leading to damage in the memory areas of the brain.
While in most cases the disease is sporadic, meaning it can occur without predisposing factors, it is also seen in people with a family history of Alzheimer’s disease.
How is early onset dementia and Alzheimer’s diagnosed?
Many people with early onset dementia face difficulty with getting an accurate or timely diagnosis, as well as increased medical costs and lack of proper medical care. This is because early onset dementia is uncommon and symptoms are often misinterpreted, leading to delays in diagnosis and untreated disease progression.
In general, diagnosis is made by examining:
- Family history
- Duration of presenting complaints of dementia
- Cognitive tests to assess memory, problem-solving, or other mental skills
- Blood tests and urine tests to assess whether there are abnormal protein levels in the body
- Computed tomography (CT) and magnetic resonance imaging (MRI) scans to assess the extent of tissue damage in the brain
What treatment options are available for early onset dementia?
Treatment options include medications to slow down nerve tissue damage, including:
Currently, there is no cure for dementia, although research is underway to find more effective treatment options to slow down the progression of the disease.

16 Early Signs of Dementia
Dementia is a general term for a group of conditions characterized by a decline in memory, thinking and reasoning. The early signs of dementia may vary depending on the cause of dementia. Some of the early signs include a decline in memory, inability to focus, forgetfulness and other symptoms.
Alzheimer's Disease
Alzheimer's disease is a common cause of dementia. Symptoms and warning signs of Alzheimer's disease include memory loss, difficulty performing familiar tasks, disorientation to time and place, misplacing things, and more. The biggest risk factor for Alzheimer's disease is increased age. Treatment for Alzheimer's is often targeted toward decreasing the symptoms and progression of the disease.
benztropine
Benztropine is a medication used as an adjunct therapy for the treatment of all forms of Parkinson’s disease. Common side effects of benztropine include rapid heart rate (tachycardia), confusion, disorientation, depression, memory impairment, nervousness, visual hallucinations, worsening of psychotic symptoms, toxic psychosis, lethargy, numbness of fingers, absence of sweating (anhidrosis), high body temperature (hyperthermia), and others. Safety of use in pregnancy is not established, avoid use. Anticholinergic medications may suppress lactation and it is not known if it is excreted in breast milk, avoid use.
Dementia Foods: Foods that May Lower Dementia Risk
What foods are associated with Alzheimer's disease and other forms of dementia? Cognitive function is predicated on good nutrition. Learn how vegetables, whole grains, and lean proteins like fish can lead to a healthier brain. Discover why foods that stave off heart disease are good for brain function.
Dementia
Dementia is defined as a significant loss of intellectual abilities such as memory capacity, severe enough to interfere with social or occupational functioning. There are several different types of dementia, including cortical, subcortical, progressive, primary, and secondary dementias. Other conditions and medication reactions can also cause dementia. Dementia is diagnosed based on a certain set of criteria. Treatment for dementia is generally focused on the symptoms of the disease.
Bad Brain Health Habits
Good brain health depends on exercising regularly, eating well, and getting enough sleep. Learn how to develop good health habits to protect your brain against neurodegeneration, Alzheimer's disease, and other kinds of dementia.
The Stages of Dementia: Alzheimer's Disease and Aging Brains
What are the symptoms of dementia? What causes dementia? Dementia includes many disorders, such as Lewy Body dementia, Alzheimer's disease, vascular dementia, and more. Learn the warning signs of dementia.
What Is the Difference Between Dementia and Alzheimer's?
Dementia is a group of symptoms (syndrome) characterized by a decline in memory, thinking and reasoning. Although dementia is a cluster of symptoms, Alzheimer’s is a slowly progressive disorder of the brain that destroys memory and thinking skills.
Down Syndrome
Get the facts on Down syndrome, a genetic disorder caused by an additional set of chromosomes in a developing fetus. Down syndrome signs and symptoms include distinctive facial features, growth retardation, and decreased mental function and IQ. Blood tests and ultrasound may be used to screen for Down syndrome but chromosome analysis of the fetus is needed to diagnose the condition. People with Down syndrome age more quickly and may develop Alzheimer's disease as young as age 40. Sometimes people are diagnosed with mosaic Down syndrome, in which case they have more than one type of chromosomal makeup.
Early Warning Signs and Stages of Dementia
Dementia is a decline and or loss of behavior of mental abilities, loss of judgment, language, and reasoning. Early warning signs of dementia include misplacing items, difficulty planning or problem solving, poor work performance, difficulty doing familiar tasks, and withdrawal from social activities.
There are seven stages of dementia that range from stage 1, with no cognitive decline to stage 7, which is severe dementia.
Frontotemporal Dementia (FTD) Picture
Frontotemporal dementia, sometimes called frontal lobe dementia, describes a group of diseases characterized by degeneration of nerve cells - especially those in the frontal and temporal lobes of the brain.
