Top 5 Causes of Early-Onset Dementia in Douglas County

Early-onset dementia is the generic term used when cognitive impairment develops in adults under the age of 65. The initial symptoms often include difficulties with language and vision along with behavioral or personality changes. There are some key reasons why the disorder develops. 

1. Familial Alzheimer’s Disease

This form of dementia develops secondary to inheriting one of three abnormal genes: 

  • Amyloid precursor protein (APP)
  • Presenilin 1 (PSEN1)
  • Presenilin 2 (PSEN2)

Adults who inherit one of these anomalies are certain to develop familial Alzheimer’s. Their offspring have a 50 percent chance of inheriting the causative gene and also developing the disorder. However, early-onset dementia can also occur in someone due to environmental and lifestyle factors. 

If your loved one has recently been diagnosed with Alzheimer’s, now is the best time to plan for long-term care at home. Families shouldn’t have to worry about finding reliable home care providers.

2. Vascular Dementia

Cognitive decline occurs in this instance due to a blockage that interferes with normal blood flow throughout the brain. Vascular dementia remains the second leading cause of cognitive impairment, and it is commonly associated with someone who experienced a stroke. However, vascular issues can also occur due to traumatic injury, high blood pressure, high cholesterol, or diabetes. Reducing risk factors and managing current health conditions can prevent dementia development. 

3. Frontotemporal Dementia

Frontotemporal dementia (FTD) is a general term referring to disease processes that cause deterioration in the frontal lobe of the brain. The affliction may also progress to the temporal lobes. Unlike other forms of dementia, FTD has strong genetic ties. Adults either have a family history of frontotemporal dementia or have mutations in the GRN or MAPT genes. Currently, there is no cure for FTD. Physicians only offer symptomatic management.

4. Alcohol-Related Dementia

Alcoholism causes dementia in several ways. Heavy drinking permanently damages neurons, as alcohol is toxic to the brain cells. Drinking also stimulates chemical changes in the brain and shrinkage of tissues. Alcoholics commonly turn away from eating properly in favor of drinking, which causes malnutrition. When the gastrointestinal system is constantly exposed to alcohol, irritation occurs that leads to vomiting and malabsorption of nutrients. Chronic drinkers are commonly deficient in thiamine, which is necessary for healthy neuron function. Over time, drinking damages blood vessels and causes high blood pressure. LDL cholesterol levels also rise, which further impedes blood flow to the brain. Becoming and staying sober can reverse the symptoms. 

5. Lewy Body Dementia

Lewy bodies are alpha-synuclein proteins that develop and accumulate in the regions of the brain that regulate cognitive ability and motor skills. The nature of the disorder prevents the use of medications, as people experience many adverse reactions. Affected adults are generally advised to participate in physical therapy, cardiovascular training, and strength training along with performing balance and stretching exercises to maintain motor skills and physical movement. Speech therapy helps adults manage speech or swallowing difficulties. Art, music, and occupational therapies are recommended to boost mood.
