Why does a person forget his mother's language after the attack on the brain?

The effects of a stroke change a person's life. One is to forget your native language or to know only one foreign language.

Such examples are rare, but there are explanations of them, says Anja Lovi, who studies language and speech therapy in the United Kingdom.

This change is not necessarily caused by a stroke but also by a head injury or a shorter coma.

Lovi addressed a British woman who, after a heavy migraine, spoke something like a French accent and a patient who spoke with a foreign accent after the vaccine.

People with a stroke or other remarkable health problems may at times be unable to express certain words. They find it difficult to find the right words and pronounce words properly until the person listening to them understands this as a foreign accent.

People do speak a foreign language. More often, this is the language they have learned throughout their life. There are even contrasting cases: A person forgets a foreign language and speaks only his mother tongue.

Very rarely is a situation when a person speaks one day in his mother tongue and another in another language.

Lovi believes that the outdated view is that foreign language and native language are in completely different parts of the brain.

Researchers have long tried to explain these disorders. After a blow, the brain does not have enough energy to build up simultaneously and earlier ties. Depending on the impulse you receive, it may be easier for a person to speak only one language.
