These diseases can include Alzheimer’s disease, Lewy body dementia, vascular dementia, and frontotemporal dementia. Dementia can be caused by damage or changes in the brain, typically in older adults. These changes and damage can be influenced by a variety of underlying causes, including brain injuries, tumors, substance use, Huntington's disease, Parkinson’s disease, infections, and the use of certain medications. 

If you are struggling with substance use, contact the SAMHSA National Helpline at (800) 662-4357 to receive support and resources. Support is available 24/7.

Are Alzheimer’s disease and dementia the same?

According to the Alzheimer's Association, Alzheimer’s disease is a type of dementia. This disease typically affects individuals over the age of 65, though it can also impact younger individuals with a condition referred to as “early-onset Alzheimer’s.” As a progressive disease, Alzheimer's can worsen over time. This can mean that individuals in the earlier stages of Alzheimer’s may not have as noticeable symptoms, while those in later stages could find it difficult to function or communicate.

This can make it difficult for family members, who may wish to correct a person’s account of events or perspective. Once these paranoid patterns of thought turn into firmly held beliefs, they may be referred to as delusions.

• Think that their partner is going to be harmed
• Create false accusations against someone based on no evidence
• Believe that a government organization wants to kidnap them
• Think that the staff members of a facility are taking their belongings

A person experiencing delusions may also have other types of severe delusions and untrue beliefs. These can include delusions of reference, which can cause someone to think they are receiving special communications, and grandiose delusions, which can lead someone to believe they are significantly important or possess supernatural abilities. 

What conditions can cause delusions and paranoia?

These can include mental disorders like schizophrenia and dementia-related diseases.

How can dementia affect your physical health

• Difficulties with movement
• Loss of control over bladder and bowels
• Difficulty eating and drinking
• Stiffness in the muscles
• Fatigue
• Sleep disturbances
• Seizures

Dementia can also cause a person to have difficulty with self-esteem, as they may lose confidence in their ability to complete certain tasks. As dementia progresses, a person may have difficulty remaining employed or maintaining relationships, which can further damage their self-esteem. 

Treatments for dementia and symptoms like paranoia

Treatment for dementia diseases and their symptoms can vary, often including the use of medication and therapy. Medications can include anti-amyloid treatments, cholinesterase inhibitors, and glutamate regulators. These medications may help to slow the progression of certain dementia diseases, reduce the severity of symptoms, and help individuals retain their memory, attention, and reasoning abilities. 

What therapeutic approaches can help people with dementia?

In addition to medications, therapeutic approaches can be essential for coping with the symptoms of dementia. These approaches may include cognitive stimulation therapy (CST), life story and reminiscence work, and cognitive rehabilitation.

• Cognitive stimulation therapy (CST): CST typically involves a provider discussing interests, past events, memories, and current information with an individual experiencing dementia. This may help them to build their concentration, reduce memory loss, and improve thinking skills, while also serving as a way to practice communication. 
• Life story and reminiscence work: Life story therapy can offer a way for those with dementia to create a narrative from their life experiences that they can more easily understand. This can involve discussing important events, people, and places from their past. By doing so, they may be able to more easily remember their past and connect it to their present. 
• Cognitive rehabilitation: Cognitive rehabilitation therapy can help those with dementia to maintain specific skills or learn new ones. These may include using certain pieces of technology, cooking, remembering appointments, and anything else that may be beneficial. 

Online therapy for those with paranoia or dementia

While these therapeutic approaches can be beneficial, in-person forms of therapy may not always be available. Some individuals with dementia may not have a means to travel to a therapist's office. Others may find it difficult to navigate the process of scheduling an in-person appointment or prefer to use other forms of communication, such as texting, calling, or video chats. In these situations, it may be beneficial to explore alternatives, such as online therapy. Research suggests that online therapy can be as effective as in-person therapy, with no significant differences between symptom severity after treatment, client satisfaction, and overall improvement.
