Dear abigail, it's good to see a post from you again, I'm glad you came back.
this post brought to my memory a neighbor of my parents' house, she sometimes had attacks, mood changes, took pills to sleep and had her in control with a specialist, she had a dementia, but I do not know what type it was, but She was young when she began to suffer from this disease,and Alzheimer's, is an existing disease in my maternal family, many of the adults have died not knowing who they were themselves, because they lost their memory totally, this disease that terrifies me has led me to read a lot about it.

Affectation of personality, behavior and language is greater than in Alzheimer's disease, while memory impairment is lower.

Dementia is the slow and progressive decline of mental function, including memory, thinking, judgment and the ability to learn. Dementia is different from delirium, characterized by inability to pay attention, disorientation, inability to think clearly and fluctuations in alertness.

Dementia mainly affects memory, while delirium mainly affects the ability to pay attention.

Dementia usually begins little by little and has no definite starting point. Delirium begins suddenly and often has a definite start time.

Approximately one in 10 dementias is frontotemporal. In general, dementia develops in children under 65 years of age. Men and women are affected approximately equally.

Alzheimer's is the most common form of dementia. Dementia is a general term to describe the loss of memory and other intellectual abilities and is so severe that it interferes with the individual's daily life. Alzheimer's accounts for 60 to 80 percent of the cases of dementia, It is a brain disease that causes problems with memory, the way of thinking and the character or the way of behaving.

Alzheimer's gets worse over time and is fatal. Although there are many symptoms, most people experience severe memory loss that affects daily activities and the ability to enjoy hobbies that the person enjoyed previously. Other symptoms are confusion, disorientation in familiar places, placement of objects out of place.

It is very sad to see how our loved ones forget about us and even about themselves, for my opinion it is a death in life, but it is good to know that there are preventive methods, thank you very much for the friendly information, good post ....
