levels can create depression. Similar to dopamine‚ there are addictive‚ dangerous drugs that can alter the serotonin’s levels in the brain. A drug that is capable of altering the serotonin levels is ecstasy. Serotonin is usually not released all at once; however‚ drugs like ecstasy cause serotonin to release all at once which creates strong feeling of accomplishment and an increase in self-esteem. Similar to methamphetamine and cocaine’s effects on dopamine levels‚ anti-depressants help to keep serotonin

of dopamine. Dopamine is a brain chemical that increases the sensitivity of the brain cells that promote the individual’s awareness of events around her or him when in danger or aroused and when under stress. If‚ however‚ the individual’s level of brain activity is already highly aroused‚ then the effects of additional dopamine activity may trigger the onset of a psychotic state‚ such as schizophrenia. Seeman (1987) reviewed a number of studies and found a 60-110 density increase in dopamine receptor

causes ADHD. These genes involve the dopamine receptors or transporting molecules (Batts). “Some of these genes may increase dopamine receptors on certain parts of the brain which may have the effect of depleting dopamine” (Batts). Let’s rewind for a second. ADHD is classified as a neuropsychiatric disorder. Neuro relating to nerves or the nervous system of the brain. The brain has a specific neurotransmitter deficiency‚ norepinephrine. Norepinephrine requires dopamine in order to function correctly.

Also‚ even within the biological approach‚ there are various different biological factors that cause conflict with each other‚ e.g. genetic tendency‚ the dopamine hypothesis (a chemical issue)‚ innate brain structures‚ and diathesis-stress model. Firstly‚ the Gottesman and Shields study‚ which supports the genetic approach‚ can be seen as less generalisable due to its limited sample and as the participants

theory on Schizophrenia is a determinism theory which states that Schizophrenia is caused by our genetics and things that are involved in our bodies. The biological theory states that the cause of Schizophrenia is due to issues such as our genes‚ and dopamine levels‚ and therefore it can be cured by looking at these issues. The first biological explanation I will look at is the genetic theory of Schizophrenia. There is a 1% chance of someone having schizophrenia in general‚ however this figure increases
