Dementia is a disease that has a set of symptoms that may include memory loss and difficulty in thinking. A person diagnosed with this usually has difficulty with their problem-solving and language skills. Experiencing mood swings or change in behavior often occurs as well, affecting the daily life of the patient.

Hiring dementia caregivers in Chicago, or anywhere around the world, is often an option for families with a loved one experiencing this. Safety should be your main priority and having a well-trained professional to take care of your loved one is a good step to help them take their medications on time as well as address other concerns.

Here is a list of the different types of dementia to help you understand your loved ones more:


This is the most common type of Dementia. Between 60 to 80 percent of cases is caused by this. Early signs include depression and forgetting names and recent events. Alzheimer’s causes the brain cells to die, which leads the chemistry of the brain to change, making the patients experience confusion. They also have trouble with speaking and writing. Usually, this is developed during a person’s old age; but there is a 5% chance of it occurring when a person is in his/her 40s or 50s.

Vascular Dementia

This is the second most common type of Dementia. It happens as a person gets old, after a stroke, or if a person has an advanced heart disease. Vascular Dementia is caused by the lack of blood flow in the brain. Symptoms would either occur slowly or suddenly depending on what caused it. This, then, causes a person to have vision problems or sometimes hallucinations. During the early stages, confusion and disorientation are the usual struggle of a person diagnosed with this. Moreover, there is a high chance later on that the patient would experience trouble completing tasks because of their diminishing concentration skills.

Parkinson’s Disease (PD)

This is a long-term degenerating disorder in the central nervous system, which affects the motor system. During the early stage, a person experiences shaking, slowness in moving, and difficulty in walking.

People with advanced PD develops Dementia in the long run. They would have problems in reasoning and judgement, which would cause them to have trouble in understanding visual information and usually forgets how to do daily tasks. As the disease progress, a person often has hallucinations, which may cause depression and paranoia. This type of Dementia can also cause the person to become irritable.

Lewy Body Dementia

This disease shares similar symptoms with Parkinson’s and Alzheimer’s (such as trembling hands, trouble walking, and feeling weak). Lewy Body Dementia is caused by protein deposits in nerve cells, which interrupts chemical messages in the brain making the person experience disorientation and fainting.

Pick Disease

This disease causes irreversible dementia that causes emotional, behavioral, and neurological symptoms, which get worse overtime. There is still no known cure for this. Pick disease is also known as Frontotemporal dementia, a term commonly used to describe many types of dementia. It damages the front and back of the brain and affects people as young as 45 years old. Scientists still don’t know where it came from but it is usually hereditary.

Creutzfeldt-Jakob Disease (CJD)

Out of a million, only one is diagnosed with Creutzfeldt-Jakob Disease in a year. This is one of the rarest forms of Dementia. It progresses very quickly and a victim dies within a year of its diagnosis. Its symptoms are often similar with other Dementia diseases. Experiencing agitation while having depression, confusion, and memory loss are just a few of them.

Mixed Dementia

Mixed Dementia is very common but 45% of people, who has Dementia doesn’t know they are suffering from it. Its usual combinations are Alzheimer’s and Vascular Dementia. The symptoms vary from different people but generally, patients suffer from change of behavior and mood swings. As the disease progress, difficulty in walking and speaking also occur.

Normal Pressure Hydrocephalus

Normal Pressure Hydrocephalus or NPD is a disease, which causes the person to have excess fluid in the brain ventricles. To function well, the brain and spinal cord should have only the right amount of fluid. Excessive fluid causes the brain to have extra pressure, which damages it and causes the victim to experience dementia symptoms. An estimate of 5% of dementia cases is due to NPH.
