Senile Dementia: Symptoms, Causes & Treatment

Senile dementia is a neurodegenerative condition that affects older adults and gradually impairs several cognitive functions, including memory, reasoning, language, and the ability to carry out daily activities.

The term senile dementia has historically been used to describe cognitive decline in older adults. Today, the preferred medical term is simply dementia.

If symptoms suggestive of dementia are present, it is important to see a neurologist or primary care provider for a proper evaluation. Depending on the case, treatment may include medication, physical therapy, and occupational therapy.

Main symptoms

Depending on the cause, symptoms of dementia may include:

• Memory loss

• Difficulty communicating

• Confusion, disorientation, and personality changes

• Difficulty recognizing family members and friends

• Agitation and wandering at night

• Loss of appetite and weight loss

• Urinary and fecal incontinence

• Repetitive movements and speech

A person with dementia may also have difficulty doing simple daily tasks and taking care of personal hygiene.

According to the World Health Organization, dementia affects memory, other cognitive abilities, and behavior in ways that can significantly interfere with everyday functioning.

These changes can lead to increasing dependence and, in some people, may also contribute to depression, anxiety, insomnia, irritability, delusions, and hallucinations.

Confirming a diagnosis

Dementia is usually diagnosed by a neurologist based on symptoms, personal and family medical history, a physical exam, and cognitive and neuropsychological tests.

To confirm the diagnosis, the doctor may also order blood tests and brain imaging, such as magnetic resonance imaging (MRI) or computed tomography (CT). According to the National Institute on Aging, brain scans and other tests can help identify signs of dementia and rule out other possible causes of brain changes.

Stages of dementia

The stages of dementia are:

1. Early stage

In the early stage of dementia, symptoms are usually subtle and may be mistaken for normal age-related changes.

The main features of this stage include difficulty with concentration and short-term memory, as well as trouble judging distances or recognizing hazards, which can increase the risk of tripping or bumping into objects.

There may also be difficulty finding words or names, a greater tendency to forget where objects were placed, and trouble finding one’s way even in familiar places.

2. Middle stage

At this stage, symptoms become more noticeable and have a major impact on daily life. The person may develop behavioral changes and become more suspicious, anxious, or aggressive.

The person may also forget recent conversations or activities and have trouble recognizing close family members and friends.

In addition, the person may become disoriented in time and place, which can cause them to get lost even in familiar settings.

3. Advanced stage

This is the most severe stage, in which the person loses much of their independence and may become unable to communicate, express needs, or engage in social interaction.

In addition, the person may lose the ability to perform basic tasks such as eating, getting dressed, or cooking, becoming fully dependent on caregivers and medical support.

Difficulty walking or moving may cause the person to become confined to their bed, increasing the risk of complications related to immobility. Urinary and fecal incontinence is also common.

Possible causes

The main causes of dementia include:

1. Alzheimer’s disease

Alzheimer’s disease is characterized by the progressive degeneration of neurons and impairment of cognitive functions such as memory, attention, language, orientation, perception, reasoning, and thinking.

The exact causes are still unknown, but studies suggest a hereditary component, especially when it begins in middle age.

2. Vascular dementia

This type tends to have a faster onset and is associated with multiple brain infarctions, usually along with high blood pressure and stroke.

Brain impairment is more evident in complex attention, such as processing speed, and in frontal executive functions, such as movement and emotional response.

3. Dementia caused by medications

Some medications, when used regularly, may increase the risk of developing dementia, such as antihistamines, sleep medications, antidepressants, medications used for heart or gastrointestinal problems, and muscle relaxants.

4. Other causes

Other conditions may also lead to dementia, including Lewy body dementia, Korsakoff syndrome, Creutzfeldt-Jakob disease, Pick’s disease, Parkinson’s disease, and brain tumors.

Treatment options

Treatment for dementia varies depending on the cause. A doctor may prescribe medications such as acetylcholinesterase inhibitors, antidepressants, mood stabilizers, or antipsychotics.

The doctor may also recommend physical therapy exercises, occupational therapy, and guidance for family members and caregivers, among other measures.

It is essential for a person with dementia to receive ongoing medical follow-up and support at home to help improve quality of life and make treatment easier.
