Can schizophrenia be inherited?

GENETIC schizophrenia

Schizophrenia is a mental disorder that affects a significant part of the world's population. For years, schizophrenia has been the subject of thorough research, in order to understand both its causes and its treatments. One of the most important questions is whether schizophrenia can be inherited, and if this happens, what role will genetic factors have in the development of said mental disorder?

In the following article we are going to clear up all doubts about whether hereditary schizophrenia and What implications could this fact have? in those people who have a family history of said disorder.

What is schizophrenia

Schizophrenia is a mental disorder that directly affects the way how a person thinks, feels and behaves. It is characterized by a series of symptoms such as hallucinations, delusions and difficulties in concentrating and maintaining attention. It is normal that schizophrenia ends up affecting the daily lives of people who suffer from these symptoms.

All this has caused researchers to study different factors, which may contribute to its development as This is the case of genetic, environmental and neurobiological factors. Among all these factors, the role of genetics has been the subject of numerous studies and research.

What are the symptoms of schizophrenia

Symptoms can be divided into several categories, including positive, negative and cognitive symptoms. It is important to keep in mind that the symptoms of schizophrenia will vary in severity and presentation in each individual. Some people may experience only some of these symptoms, while others may experience a combination of positive, negative, and cognitive symptoms. Next, we show you the most significant symptoms of schizophrenia:

Positive symptoms

  • Hallucinations such as hearing voices or seeing things that are not real.
  • Delusions or false beliefs that cannot be changed with rational arguments.
  • Disorganized thoughts. This can manifest itself in inappropriate responses to certain questions or incoherent conversations.

negative symptoms

  • Decrease in the quantity or quality of speech, which translates into brief or poorly elaborated responses.
  • Lack of emotions.
  • Social isolation or little interest in maintaining social relationships.
  • Inability to have some pleasure in life.

Cognitive symptoms

  • Certain difficulties related to memory: problems remembering information or difficulty concentrating.
  • Relative difficulties to the atenttion.
  • Problems to be able plan, organize and carry out complex tasks.


Is schizophrenia hereditary?

The question about whether schizophrenia can be inherited has raised much controversy and debate over the years. Numerous studies have investigated the possible connection between schizophrenia and genetics, and most of these studies have concluded that there is some genetic predisposition to the disease.

It is believed that the risk of developing schizophrenia It is 1% in the general population. However, this risk will increase in those people who have a family history of the disease. In this way, it has been confirmed that siblings of people with schizophrenia have a ten times greater risk of developing the disease compared to the rest of the population.

Despite this, we must emphasize the fact that genetics is not the only factor that will contribute to schizophrenia. This is why it is thought that the interaction between genetic and environmental factors, will play a crucial role in the development of schizophrenia. In this way, it has been shown that stress suffered during pregnancy or certain traumatic experiences can increase the risk of developing schizophrenia in people with a genetic predisposition.

Although it has been scientifically proven that schizophrenia has a genetic component, doubts remain about the existing relationship. between genetics and schizophrenia itself. A variety of genes have been identified that may be associated with an increased risk of suffering from schizophrenia, but the way in which these genes interact with each other and with environmental factors continues to be the subject of research today.


The social implications of schizophrenia

Recognition of the genetic contribution to schizophrenia It will have important clinical and social implications. On the one hand, understanding the genetic factor of the disorder will help doctors identify people who are most at risk and provide them with early interventions as well as appropriate treatments. This will include cognitive-behavioral therapies, antipsychotic medications and psychosocial support with the aim of helping people manage their symptoms and improve their quality of life.

On the other hand, the certainty that schizophrenia has a genetic basis will have quite significant social implications. For example, some people may feel great fear due to society's perception that the disease is "hereditary" and that they could pass it on to their own children. However, it is important to note that having a family history of schizophrenia does not have to imply that someone in the family will develop the disease, since the vast majority of people with a family history will never develop symptoms.

In summary, there is no doubt that schizophrenia has a clear genetic basis, with some evidence suggesting that people with a family history of the disease have a higher risk of developing it than other people. However, genetics is not the only factor present in the development of schizophrenia, since the interaction between genetic and environmental factors plays a key role in its development. That is why a comprehensive approach to this disorder must be carried out with the aim of improving the prevention, diagnosis and treatment of schizophrenia and helping to improve the quality of life of those people who suffer from such a mental disorder.
