Aphasia is a language disorder resulting from damage to brain regions that control language, and it is categorized into different types. The main types of aphasia are:

Wernicke's Aphasia: In this type, individuals know what they want to say but struggle to select the correct words and express sentences properly. They often speak fluently, but their speech can be meaningless or jumbled.

Broca's Aphasia: Individuals with Broca's aphasia have difficulty putting words together to convey their ideas. Speech is typically slow, effortful, and hesitant; they struggle to form complete sentences or written expressions.

Anomic Aphasia: Individuals with this type of aphasia experience significant difficulties remembering and using the correct words, especially nouns. While their speech is generally fluent and grammatically sound, they struggle to find appropriate words for objects, people, or places (word-finding difficulty).

Global Aphasia: Considered one of the most severe types of aphasia, individuals with global aphasia experience widespread and severe difficulties in both language comprehension and expression. They can often produce very few words or may not speak at all; sometimes they can only utter repetitive phrases or single sounds.

Progressive Aphasia (Primary Progressive Aphasia - PPA): This type of aphasia typically begins with mild symptoms but gradually worsens over time. Individuals' abilities to speak, understand language, read, and write progressively decline, and symptoms worsen with age.
