  • We all have an inner dialogue inside our mind - reminding yourself to pay your cellphone

  • bill, or even rehearsing a tough conversation with a friend. But what if that voice becomes

  • voices that are out of your control?

  • Psychologist Julian Jaynes proposed a theory that, not so long ago all humans heard voices

  • - created internally from the right hemisphere of the brain, but perceived as external from

  • the left hemisphere (bicameralism). As a result these voices were perceived as communication

  • from the gods. But around 1000 BC, with the rise of modern consciousness, these voices

  • became recognized as our own. Some psychiatrists believe that the brains of schizophrenic people

  • may revert to this state, and not recognize some of their thoughts as their own.

  • Schizophrenia is a disease of the nervous system, affecting approximately 1% of the

  • population. To be clear, schizophrenia is not the same as havingmultiple personality

  • disorder’. Symptoms often include hallucinations: from seeing things that aren’t there, to

  • delusions such as a higher belief in conspiracy, higher rates of depression, and most notably

  • hearing voices. Auditory hallucinations occur in many disorders - from simple sounds to

  • words or names being called - but the voices heard in schizophrenics are quite different.

  • They are often associated with their current mental state, and can be quite hostile, accusing,

  • threatening or persecuting (58); ultimately embodying many of their fears.

  • A 2006 study of over 3000 schizophrenic patients found that genes related to immune function

  • may play a role - specifically the complement component 4 or C4 genes. C4 is a gene involved

  • in trimming the synapses in the brain; for example, teenage brains undergo a process

  • known assynaptic pruningin which unused connections are cut away to aid in our brains

  • efficiency. But in individuals with schizophrenia, this C4 gene may be overactive and cut down

  • areas that are involved in planning, cognition and thinking. Links have also made between

  • microbes in the gut - after all, the microbes that live within us have also been shown to

  • modulate immune response and impact brain development. One study found that lactic acid

  • bacteria were significantly more abundant in people with schizophrenia, while another

  • found that the prevalence of lipid and glucose abnormalities is much higher in patients with schizophrenia.

  • And while diagnosing schizophrenia is primarily based on behavior and reported experiences,

  • research has found the cause to be a combination of these genetic factors along with some environmental

  • stressors like growing up in an urbanized area, minority group position, and even cannabis

  • use as THC can exaggerate psychotic response in some individuals with genetic risk or developmental trauma.

  • Currently, medication for schizophrenia mostly focuses on combating hallucinations and delusions

  • but, unfortunately, 49.5% of schizophrenia patients don’t end up taking their medicine.

  • This is why genetic research is so important to combatting this disease. Of course, some

  • people can and do recover through a combination of medication, counselling and support which

  • can greatly reduce the symptoms.

  • On AsapTHOUGHT we talk about how mental health stigma is a serious issue in our culture and

  • the media. Many of us negatively contribute to the stereotyping of mental illness without

  • even realizing it - so we break down 5 ways we can all reduce mental health stigma right

  • now. Check it out with the link below.

  • at This week we wanted to recommend the bookSchizophrenia: Understanding

  • Symptoms Diagnosis & Treatmentwhich tackles much of the stigma tied to schizophrenia and

  • how it affects those with the condition. You can get a free 30 day trial at
