Alcohol consumption has many negative effects on the human body, and has been proven to have teratogenic effects on fetal development. Prenatal alcohol exposure (PAE) is associated with growth deficits and neurodevelopmental disorders, including fetal alcohol spectrum disorder (FASD). Despite such effects, there are still many women who do not give up the consumption of alcoholic beverages during pregnancy. This article, based on a review of available studies on PubMed, examines whether prenatal alcohol exposure can cause problems in children's speech development and promote communication problems in children, as well as in adolescents.  Longitudinal observations on prenatal alcohol exposure (PAE) have shown that children up to the age of 3 after PAE have difficulties in receptive or expressive communication compared to a group not prenatally exposed to alcohol. Alcohol has been shown to be the overriding factor causing disorders in the development of the brain and nervous system, which are the main structures responsible for the process of speech development and also the formation of communication skills. Studies among adolescents with PAE have shown that they have weaker spoken and written language skills than those without PAE or with low PAE. This also translates into difficulties in developing their communication skills, which can make it much more difficult for them to become independent and move smoothly through the difficult period of adolescence.

Social media (SM) is now a popular place for content creation and a means of communication between young adults. Their increasing participation in our lives means that they replace us face to face contacts (FTF), which can affect our mental health. The above changes in communication habits may correlate with the occurrence of depressive states and a sense of social isolation. The aim of the study is to analyze the relationship between the use of MS and the occurrence of depressive states in young adults on the basis of selected literature. The topic of emotional support and a sense of social isolation will also be discussed. PubMed and Google Scholar databases were used to select the appropriate literature, and only research was used.  The cited studies on the use of MS and depression showed that people who spent the most time on social media showed an increased risk of experiencing a depressed mood. Another study analyzed the likelihood of depression depending on the method of emotional support. The comparison of emotional support in FTF (face to face) communication with the support obtained through MS showed that the possibility of depressive symptoms was lower for FTF communication and higher for the second method, respectively. The use of social media among young adults contributes to an increased risk of depression, perceived social isolation and reduced emotional support. Moreover, it has been proven that addiction to MS positively correlates with the presence of depressive symptoms.
