What causes poor intelligence?

Generally, poor intellectual development may be caused by genetic factors, unhealthy dietary habits, environmental factors, and other reasons. It is recommended to improve educational approaches, adjust dietary habits, and use medications under the guidance of a physician for treatment.

1. Genetic factors: Genes play a decisive role in intellectual ability. Since genes are usually inherited from parents or grandparents, abnormalities in chromosomes from these relatives may lead to poor intellectual development. Early intervention through active education can often help improve outcomes.

2. Unhealthy dietary habits: If a patient's diet is nutritionally unbalanced over time, it may result in deficiencies of essential nutrients, thereby affecting intellectual development and leading to cognitive impairment. This can be improved by avoiding a monotonous diet, ensuring dietary diversity, and refraining from consuming foods high in heavy metals.

3. Environmental factors: Exposure to harmful substances such as mercury, lead, and other heavy metals in one’s living or working environment may damage brain cells and result in impaired intellectual function. Under medical supervision, medications such as dimercaprol injection or sodium dimercaptopropanesulfonate injection may be used for treatment.
