How does being bilingual affect your brain? It depends on how you use language
Studies on suggest bilinguals and monolinguals
Some research found speaking more than one language can potentially improve your cognitive processes. But other studies found that bilinguals and monolinguals perform similarly.
Some studies suggest bilinguals and monolinguals use the brain differently to complete an executive function task, even if the performances are similar. Other studies found differences in brain structure, but how these differences manifest is inconsistent.

The Reason For Neuroplasticity: Neuron Cells
While neuroplasticity is the ability of the brain to form fresh connections and to rewire itself, neurogenesis is the brain’s ability to grow new neurons.
Experiments in the 1960s discovered that traumatic events, stress and anxiety are detrimental to the neuron cells of the brain. This led to new understandings about the brain being a regenerative organ, where cells can regrow and replenish, also known as neurogenesis.
Principles Of Neuroplasticity
Neuroplasticity has two broad types:
- Structural neuroplasticity: When the synapses or the strength of connections between neurons changes.
- Functional neuroplasticity: When learning and development lead to permanent changes in the synapses.
Just like medications and chemicals change our brain, neuroplasticity has the potential to reinvent oneself and get over the traumatic events of the past. It has the power to dissolve our hardwired memories which are fear-based.

Forgetting the First Language
While our brains are flexible and adaptable as children, we tend to start having more rigid learning and relearning skills as we grow old.

Trauma associated with a Language
One of the reasons for forgetting a language is the trauma associated with speaking a particular language: The mind recalls the bad experiences while the language is heard or spoken.
The Switch Mechanism
Once a person is able to speak two or more languages, the mind has to create a mechanism to switch between those seamlessly.
Switching a language is not like forgetting, but if there is too much back and forth, the competition starts between the two languages.
