Can A Chemical Imbalance Cause Anger
Just so, what are the signs of a chemical imbalance?
- feelings of sadness, helplessness, worthlessness, or emptiness.
- overeating or loss of appetite.
- insomnia or sleeping too much.
- a feeling of impending doom or danger.
- lack of energy.
- distancing yourself from others.
Furthermore, is anger a sign of mental illness? Many things can trigger anger, including stress, family problems, and financial issues. For some people, anger is caused by an underlying disorder, such as alcoholism or depression. Anger itself isn’t considered a disorder, but anger is a known symptom of several mental health conditions.
Considering this, what Mental Illness Causes Anger?
Intermittent explosive disorder is an impulse-control disorder characterized by sudden episodes of unwarranted anger. The disorder is typified by hostility, impulsivity, and recurrent aggressive outbursts. People with IED essentially explode into a rage despite a lack of apparent provocation or reason.
Can too much serotonin cause anger?
Serotonin levels affect the brain’s response to anger. Summary: Fluctuations of serotonin levels in the brain, which often occur when someone hasn’t eaten or is stressed, affects brain regions that enable people to regulate anger, new research from the University of Cambridge has shown.
Experiment 2a: Subliminal Threshold Check
To verify that all ANGER and RELAX primes were presented below the subjective threshold participants were given an additional series of 32 trials in the psychophysiological laboratory as the final experimental procedure . All task parameters remained the same, but instead of making word/non-word judgments, participants were now instructed to press 1 if the word/non-word was preceded by ANGER or 2 if it was proceeded by RELAX. After this forced choice decision, their confidence was assessed on a scale of 1 to 50 using a computerized VAS.
What Part Of The Brain Controls Fear
From a biological standpoint, fear is a very important emotion. It helps you respond appropriately to threatening situations that could harm you.
This response is generated by stimulation of the amygdala, followed by the hypothalamus. This is why some people with brain damage affecting their amygdala dont always respond appropriately to dangerous scenarios.
When the amygdala stimulates the hypothalamus, it initiates the fight-or-flight response. The hypothalamus sends signals to the adrenal glands to produce hormones, such as adrenaline and cortisol.
As these hormones enter the bloodstream, you might notice some physical changes, such as an increase in:
- heart rate
- blood sugar
In addition to initiating the fight-or-flight response, the amygdala also plays a role in fear learning. This refers to the process by which you develop an association between certain situations and feelings of fear.
What Is The Name Of The Brain Chemical Released When You Are Angry
Anger takes on a different meaning when the person in question has a psychological disorder prompting the anger. When a person suffers from a paranoid or delusional disorder that leads to anger, it may be much more than simple chemical reactions causing the anger. In fact, many people who suffer from one of these disorders have a much higher likelihood of also suffering from an additional mental disorder or substance abuse -oftentimes referred to as comorbidity- which may prompt anger and aggression much more frequently than seen in people without these disorders. Delusions statistically lead to a higher chance of anger and aggression in individuals, although the actual chemical causing delusions may not be easy to pinpoint depending on the cause of the delusions.
It is also interesting to note that anger, and the intensity to which it is displayed and acted upon, is thought by many to be inheritable either genetically or environmentally. People with parents who are quick to anger may themselves be more likely to be quick to anger as well, either because they inherited the chemical reaction or because this is what they were taught.
The Role Of Biology In Aggression
Aggression is controlled in large part by the area in the older part of the brain known as the amygdala . The amygdala is a brain region responsible for regulating our perceptions of, and reactions to, aggression and fear. The amygdala has connections with other body systems related to fear, including the sympathetic nervous system, facial responses, the processing of smells, and the release of neurotransmitters related to stress and aggression.
In addition to helping us experience fear, the amygdala also helps us learn from situations that create fear. The amygdala is activated in response to positive outcomes but also to negative ones, and particularly to stimuli that we see as threatening and fear arousing. When we experience events that are dangerous, the amygdala stimulates the brain to remember the details of the situation so that we learn to avoid it in the future. The amygdala is activated when we look at facial expressions of other people experiencing fear or when we are exposed to members of racial outgroups .
Although the amygdala helps us perceive and respond to danger, and this may lead us to aggress, other parts of the brain serve to control and inhibit our aggressive tendencies. One mechanism that helps us control our negative emotions and aggression is a neural connection between the amygdala and regions of the prefrontal cortex .

Teaching Children How To Express Anger
Expressing anger appropriately is a learned behaviour. Suggestions on helping your child to deal with strong feelings include:
- Lead by example.
- Let them know that anger is natural and should be expressed appropriately.
- Treat your childs feelings with respect.
- Teach practical problem-solving skills.
Chemicals Hormones And The Brain
Some of these neurotransmitters, such as norepinephrine, are also hormones or have some effect in releasing hormones in the body. Adrenaline, cortisol, melatonin, and other hormones can affect your mood or even influence the health of your brain.
Cortisol is a hormone released when youre stressed. Its helpful at times, but too much of it for too long can cause memory loss as you age.
Imbalances in neurotransmitters are present in many conditions, including schizophrenia, depression, bipolar disorder, autism, and Parkinsons disease. Some medications target these receptors to allow your body to receive more or less of certain chemicals, while some drugs act similar to these chemicals to invoke similar responses in your body.
Maintaining a balance in these brain chemicals and hormones is key to feeling a balanced mood. You can help maintain this health to some extent through a balanced diet, limited stress, and exercise.

Where Do Emotions Come From
The limbic system is a group of interconnected structures located deep within the brain. Its the part of the brain thats responsible for behavioral and emotional responses.
Scientists havent reached an agreement about the full list of structures that make up the limbic system, but the following structures are generally accepted as part of the group:
- Hypothalamus. In addition to controlling emotional responses, the hypothalamus is also involved in sexual responses, hormone release, and regulating body temperature.
- Hippocampus. The hippocampus helps preserve and retrieve memories. It also plays a role in how you understand the spatial dimensions of your environment.
- Amygdala. The amygdala helps coordinate responses to things in your environment, especially those that trigger an emotional response. This structure plays an important role in fear and anger.
- Limbic cortex. This part contains two structures, the cingulate gyrus and the parahippocampal gyrus. Together, they impact mood, motivation, and judgement.
The Structure Of The Brain
Before we talk about what part of the brain controls anger, it makes sense to talk about the different parts of the brain. Experts on the brain have divided it up into all kinds of different regions, but we’ll keep things simple for now.
When you think of the brain, you probably think of the top part, called the cerebrum – or more specifically the cerebral cortex. This is the rough-looking ball of grey matter that makes up the largest portion of the brain. This is the part of the brain that does things like interpret senses, initiate motion, process language, and make decisions.
Below and to the back of the cerebrum is the cerebellum. This much smaller and darker mass is primarily responsible for things like balance.
In front of the cerebellum but still under the cerebrum is what’s called the brain stem. The brain stem has the important structural job of connecting the brain to the spinal cord which in turn branches into the nerves that communicate between the brain and rest of your body. However, it is also responsible for many of your most basic bodily functions.
Just above the brainstem inside of the cerebrum are more intricate structures including the amygdala. Centrally located in the brain, the Amygdala is in the perfect position to interpret stimuli and then communicate it directly to your bodily functions. So, the most primal emotions – the ones that impact things like your breath and heart rate – are all controlled by the amygdala. That includes anger.
How To Boost Your Serotonin Levels
The following are natural ways that you can boost your serotonin levels:
- getting more exposure to sunlight
- doing plenty of exercise
- counselling and meditation
If youve been experiencing a low mood for a considerable period of time, your doctor might prescribe you an antidepressant medication known as Selective Serotonin Reuptake Inhibitors .
SSRIs are the most commonly prescribed type of antidepressants in Australia. They work by stopping the nerve cells reabsorbing the serotonin again so quickly, so that there is more available to keep transmitting messages.
The Sound Of The Fury
Turn off your phones. And televisions. And game consoles…
Everyone, from children to greatgrandparents, uses electronic media, and media use will only grow more pervasive. At least, thats how Michael Rich 91, an HMS associate professor of pediatrics at Childrens Hospital Boston, sees it.
Yet since the earliest days of television, electronic media has been a blametaker. In the fifties, people worried that television would turn children into delinquents. Today, parents fear that violent movie scenes and game scenarios will breed anger, aggression, and violence. These accusations against media, Rich believes, come down to valuesbased arguments, not scientific evidence.
In the fifties, people worried that television would turn children into delinquents. Today, parents fear that violent movie scenes and game scenarios will breed anger, aggression, and violence.
In an effort to drill down to medias true effects, Rich has launched a longitudinal survey study. Were trying to create the media exposure equivalent of the Framingham Heart Study, he says. The pilot study, now in its third wave of data collection, involves an ethnically and socioeconomically diverse group of 126 middleschool students from Manchester, New Hampshire.

Diagnosing Mental Health Conditions
Mental health conditions arent determined by using chemical tests. Your treatment plan wont be guided by such tests either.
Your healthcare provider may order blood tests to rule out other conditions, such as a thyroid disorder or vitamin deficiency. Both conditions can trigger symptoms of a mental health condition.
If an underlying illness is not determined from the tests, your healthcare provider will likely refer you to a mental health professional, such as a psychiatrist or psychologist. Theyll perform a psychological evaluation.
The evaluation will include a series of questions about your:
Some medications work on a combination of two more of the chemicals above.
Examples of these medications include:
When it comes to mental health conditions, there are likely many factors at play. Its difficult to determine whether a particular treatment will ensure a cure.
For some people, depression and other mental health conditions are episodic, which means that the symptoms come and go.
Medications might be able to help manage your symptoms, but the disorder may take a long time to go into remission. Symptoms can also come back later on.
While taking medications for a mental health condition, talk therapy techniques are also an important addition to your treatment plan.
How Brain Chemicals Influence Mood And Health
1 Minute Read
The brain communicates with itself by transmitting chemicals from one neuron, or nerve, to the other. And this regular, rapid-fire messaging plays a big role in how you feel and function each day.
These neurotransmitter chemicals are classified into two basic categories: excitatory, meaning they stimulate brain activity, or inhibitory, meaning they have a more calming effect. Learn more about a few common brain chemicals and how they impact your thinking and mood.

Drinking Alcohol Increases Aggression
Perhaps unsurprisingly, research has found that the consumption of alcohol increases aggression. In fact, excessive alcohol consumption is involved in a majority of violent crimes, including rape and murder . The evidence is very clear, both from correlational research designs and from experiments in which participants are randomly assigned either to ingest or not ingest alcohol, that alcohol increases the likelihood that people will respond aggressively to provocations . Even people who are not normally aggressive may react with aggression when they are intoxicated .
Alcohol increases aggression for a couple of reasons. First, alcohol disrupts executive functions, which are the cognitive abilities that help us plan, organize, reason, achieve goals, control emotions, and inhibit behavioral tendencies . Executive functioning occurs in the prefrontal cortex, which is the area that allows us to control aggression. Alcohol therefore reduces the ability of the person who has consumed it to inhibit his or her aggression . Acute alcohol consumption is more likely to facilitate aggression in people with low, rather than high, executive functioning abilities.
Hormones Influence Aggression: Testosterone And Serotonin
Hormones are also important in creating aggression. Most important in this regard is the male sex hormone testosterone, which is associated with increased aggression in both animals and in humans. Research conducted on a variety of animals has found a strong correlation between levels of testosterone and aggression. This relationship seems to be weaker among humans than among animals, yet it is still significant .
Although testosterone levels are much higher in men than in women, the relationship between testosterone and aggression is not limited to males. Studies have also shown a positive relationship between testosterone and aggression and related behaviors in women . Although women have lower levels of testosterone overall, they are more influenced by smaller changes in these levels than are men.
Testosterone is not the only biological factor linked to human aggression. Recent research has found that serotonin is also important, as serotonin tends to inhibit aggression. Low levels of serotonin have been found to predict future aggression . Violent criminals have lower levels of serotonin than do nonviolent criminals, and criminals convicted of impulsive violent crimes have lower serotonin levels than criminals convicted of premeditated crimes .

Brain Chemicals Involved In Aggression Identified: May Lead To New Treatments
- Society For Neuroscience
- School shootings. Muggings. Murder. Road rage. After decreasing for more than a decade, the rate of violent crime in the United States has begun to inch up again. And new studies are helping scientists gain deeper insight into the neurobiology of aggression and violence.
School shootings. Muggings. Murder. Road rage. After decreasing for more than a decade, the rate of violent crime in the United States has begun to inch up again. According to the FBI’s Uniform Crime Reporting Program, violent crime rose 2.3 percent in 2005 and 1.9 percent in 2006, the first steady increase since 1993.
And new studies are helping scientists gain deeper insight into the neurobiology of aggression and violence. One analysis of brain imaging studies has revealed that brain structures involved in making moral judgments are often damaged in violent individuals. Another study involving teenage boys suggests that disruptions in a brain region linked to impulsive, aggressive behavior may underlie a certain type of violent, reactive behavior.
Still other research has shed new light on the role that certain brain chemicals play in aggressive behavior, including in maternal aggression. And new animal studies reveal that aggressive encounters cause changes in the brains of aggressors as well as their victims that increase vulnerability to depression and immune-related illnesses.
When Emotional Brakes Fail
Depression and anger often go hand in hand
Flares and flashes. Outbursts and eruptions. The words used to describe anger tend to be volcanic. And science may explain why.
When an angry feeling coincides with aggressive or hostile behavior, it also activates the amygdala, an almondshaped part of the brain associated with emotions, particularly fear, anxiety, and anger.
This finding is one in a series from studies led by Darin Dougherty, an HMS associate professor of psychiatry at Massachusetts General Hospital, that aim to uncover why anger attacks occur in patients with major depressive disorder. Some of these patients experience angry flareups that are inappropriate to the situation and out of character for the individual. People will yell or throw things, says Dougherty. We wanted to investigate the mechanisms behind those reactions.
For these patients, angry outbursts usually stop when the depression ends. Understanding this link could provide valuable insights into these disorders and their treatment.
During angry recollections, the amygdala fired. At the same time, a part of the orbital frontal cortex, just above the eyes, also engaged, putting the brakes on emotion. Healthy people experience anger, says Dougherty, but they can suppress it before acting on it.

What Part Of The Brain Controls Anger
Much like fear, anger is a response to threats or stressors in your environment. When youre in a situation that seems dangerous and you cant escape, youll likely respond with anger or aggression. You can think of the anger response and the fight as part of the fight-or-flight response.
Frustration, such as facing roadblocks while trying to achieve a goal, can also trigger the anger response.
Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression.
Parts of the prefrontal cortex of the brain may also contribute to the regulation of an anger response. People with damage to this area of the brain sometimes
