Unveiling the Mystery: Understanding the Seven Types of Dementia

Introduction: A Brief Journey into Dementia

Dementia is not a single disease. It’s an overarching term that describes a group of symptoms affecting memory, thinking, and social abilities. These symptoms interfere with daily life, and there’s a wide spectrum of types and levels of severity. Dementia is a challenging issue that society faces, primarily due to the aging population.


Our journey today takes us through the world of dementia, exploring its different types. Each comes with a distinct set of symptoms and requires specific care. By understanding these types, we can better provide for affected individuals, offering them the compassion and care they deserve.

Let’s dive into the first type of dementia, Alzheimer’s disease, which is also the most common form.

Type 1. Alzheimer’s Disease: The Common Culprit

Alzheimer's Disease The Common Culprit


When we delve into the subject of dementia, Alzheimer’s disease stands out prominently. This form of dementia is known to account for nearly 60-80% of all dementia cases, a statistic that underscores its prevalence worldwide. It is an irreversible, progressive brain disorder that slowly deteriorates memory and thinking skills and, eventually, the ability to carry out simple tasks.

Alzheimer’s disease primarily involves the parts of the brain controlling thought, memory, and language. The disease disrupts these essential functions, leading to various symptoms that become increasingly severe over time.

The first symptom, and often the most noticeable, is the difficulty remembering newly learned information. As the disease infiltrates the brain, changes typically begin in the part that affects learning, leading to frequent forgetfulness or confusion.

As Alzheimer’s disease continues its relentless course, other symptoms start to manifest. People with Alzheimer’s may have difficulty speaking, reading, or writing.

These communication issues arise as the disease affects the brain’s language and speech centers. It becomes a struggle for them to articulate their thoughts and comprehend written or spoken language, putting up barriers to effective communication.

Another poignant aspect of Alzheimer’s disease is how it disturbs one’s sense of familiarity. Individuals suffering from this condition might begin to forget people they’ve known for years, places that were once familiar, or significant events in their life. These memory lapses can lead to feelings of confusion and frustration, painting a stark picture of the disease’s impact on personal identity and relationships. (1)
