Use of screens in children under 2 years of age: its relationship in childhood neurodevelopment
No full textBackground: Childhood neurodevelopment is the process of development of the nervous system that results in the maturation of structures, the acquisition of skills such as attention, planning, memory, language, motor control, among others; and, finally, the formation of the individual as a unique person. For this, the presence of a stimulating and psycho-affective environment is important, in addition to essential genetic and nutritional aspects, since everything influences the production of neuronal synapses, resulting in greater integration of brain functions. In recent years, an alteration in these essential characteristics for neurodevelopment has been observed due to the use of screens at an early age, specifically before the age of 2 years. Because of this, the presence of Neurodevelopmental Disorders in boys and girls has been evident, which will be raised throughout this research work. Material and methods: Carry out a systematic review from which neurodevelopment itself and the results associated with Neurodevelopmental Disorders due to the use of screens in children under 2 years of age will be understood. All information found relevant to the research question will be searched and read, creating a synthesis and its objective. Results: It was observed that neurodevelopmental conditions are not immediate from the first moment that screens are used in children under 2 years of age, but rather manifest years later in key stages of growth, such as the beginning of kindergarten or beginning school.Conclusion: The use of screens in children under 2 years of age is not indicated since it does not provide any favorable effect on development and hinders its normal process.
