Early Alzheimer's, or "Presenile Dementia", is a rare type of Alzheimer's that begins before age 65, usually between 40 and 50, and is related to hereditary genetic alterations that lead to progressive loss of cognition, resulting in symptoms such as memory failure or loss, mental confusion, aggression, and difficulty performing daily routine activities.
These genetic alterations lead to the accumulation of "tau" and beta-amyloid proteins in the brain, specifically in the part responsible for speech and memory, resulting in the development of Alzheimer's symptoms. Know how to recognize the symptoms of Alzheimer's.
When the first symptoms appear, they are often confused with excess stress or depression, and therefore the diagnosis of early Alzheimer's ends up being late.The ideal is to consult a neurologist whenever symptoms appear and there is a family history of the disease, as early diagnosis is important to start treatment and delay the worsening of Alzheimer's.
Symptoms of early Alzheimer's generally develop faster than Alzheimer's at an older age, causing a rapid loss of cognition.
The main symptoms of early Alzheimer's are:
- Vision changes, such as difficulty seeing a full picture;
- Difficulty perceiving depth;
- Difficulty recognizing faces and people;
- Decreased ability to communicate verbal or written;
- Learning difficulties of new tasks;
- Forgetting common things, such as whether you had lunch or not;
- Frequent memory failures, such as leaving home and forgetting the way to go;
- Confusion, such as not knowing where you are or what you were doing there;
- Store objects in inappropriate places, such as the phone inside the refrigerator;
- Staying silent for long periods in the middle of a conversation;
- Insomnia, difficulty sleeping or multiple nighttime awakenings;
- Difficulty doing simple math, such as 3 x 4, or thinking logically;
- Loss of movement, such as difficulty getting up on your own;
- Anguish and depression, like sadness that does not go away and the desire to isolate yourself;
- Hypersexuality, public masturbation or inappropriate speech may occur;
- Excessive irritability for not remembering certain things or not understanding a certain situation;
- Aggressiveness, such as hitting family and friends, throwing things against a wall or floor;
- Apathy, as if nothing else matters.
In the case of early Alzheimer's, the symptoms of the disease set in much faster than in the elderly and the inability to take care of oneself appears very early. Know how to recognize the symptoms of Alzheimer's in the elderly.
It is important to consult a neurologist as soon as symptoms indicative of early Alzheimer's appear, so that a diagnosis can be made and appropriate treatment initiated. This consultation is even more important in the case of people who have Alzheimer's in the family, as they have a higher risk of developing early Alzheimer's.

At what age does early Alzheimer's appear?
Usually, early Alzheimer's appears between 40 and 50 years old, however there is no exact age for it to start, as there are reports of onset at both 27 and 51 years old. The most important thing is that people who have a family history of Alzheimer's are aware of the appearance of symptoms.
How to confirm the diagnosis
The diagnosis of early Alzheimer's is made by the neurologist by evaluating the symptoms and family history of Alzheimer's, memory and cognition tests, and through imaging tests, such as MRI or CT scan of the brain.
In addition, the doctor may order clinical tests to rule out other diseases that cause memory changes, such as hypothyroidism, depression, vitamin B12 deficiency, hepatitis or HIV, for example.
The exact cause of early Alzheimer's is not fully known, but it is believed to occur due to mutations in the APP, PSEN1 and PSEN2 genes, which lead to the accumulation of proteins in the brain, such as beta-amyloid and Tau protein. This accumulation of proteins seems to cause inflammation, disorganization and destruction of neuronal cells, mainly in the areas responsible for memory and interpretation of information.
These genetic changes are hereditary, which means that early Alzheimer's is more common to run within the same family, as the mutations can be passed from parents to children.
How the treatment is done
The treatment of early Alzheimer's should be guided by the neurologist, to help reduce symptoms and delay the progression of the disease.In this way, the doctor can prescribe different drugs, such as donepezil, rivastigmine, galantamine or memantine, which help maintain mental cognitive functions. See all Alzheimer's drug options.
In addition, the doctor may also recommend the use of medication to improve sleep quality and mood, as well as psychotherapy, regular physical activity and a balanced diet, including antioxidant foods.
The treatment of early Alzheimer's must be done by a multidisciplinary team, with doctors, physical therapist, speech therapist, nutritionist and occupational therapist, so that it is possible to avoid the appearance of other symptoms and complications, and improve the quality of life.
