What Is Major Depression

How Your Brain Works When You’re Depressed | Better | NBC News

Major depression, or major depressive disorder, is a mood disorder and mental illness that causes significantly and persistently low moods. More than just feeling down for a day or two, depression causes a bad mood that you cant shake for weeks. Some of the key symptoms and signs of depression are:

  • Persistent feelings of sadness and hopelessness
  • Loss of interest in activities you normally enjoy
  • Difficulty sleeping or sleeping too much
  • Weight gain or weight loss
  • Extreme fatigue
  • Anxiety, restlessness, frustration, or irritability
  • Feeling worthless, guilty, or ashamed
  • Difficulty concentrating, making decisions, or remembering
  • Thoughts of suicide and death

You may be diagnosed with depression if you have some of these symptoms for a couple weeks or longer, if they are severe enough to disrupt your normal functioning, and if they cannot be explained by substance abuse, medications, or an illness.

Functional And Structural Brain Correlates Of Risk For Major Depression In Children With Familial Depression

We studied brain correlates of familial risk for major depression.

At-risk children exhibited hyperactivation to fearful faces compared to controls.

At-risk children exhibited hypoactivation to happy faces compared to controls.

At-risk children exhibited reduced amygdala volume compared to controls.

These results identify trait neurobiological underpinnings of risk for depression.

Conclusion And Future Direction

In vivo MRI scans have made great achievements in the study of psychiatric disorders, which have resulted in the dawn of the understanding of the pathophysiology of psychosis, especially of MDD. Many brain region alterations have been reported, and some crucial circuits have also been revealed via imaging studies. The discovery of brain network put forward new ideas in the understanding of the disease of depression, providing effective stimulation sites and efficacy evaluations for the commonly used transcranial magnetic stimulation or deep brain stimulation techniques. In addition, these findings also suggest that MDD is not only due to local lesions but is also a multiloop disorder. However, previous studies still had limitations, and more research is needed in the future. First, most of the studies mentioned small sample sizes, which could have increased the falsepositive and falsenegative rates of the results. Therefore, multicenter cooperation not only would solve this problem of sample content but also could result in more indepth research. Second, the identification of significant lesions relies on longterm followups and the comparison of treated and nontreated patients. Future studies need to conduct longitudinal studies with larger samples. Moreover, using animal experiments to verify the neuroimaging findings and applying the results to humans is very important and will be a big step in the application of neuroimaging to the clinical field.

The Toll Depression Takes On The Body

Depression is much more than just a brain disorder. It causes physical symptoms and can cause lasting damage to the body because of both direct effects and indirect complications of living with this mental illness. For instance, depression can change your appetite. It may trigger you to eat less and lose an unhealthy amount of weight. Or it can cause you to eat more, leading to weight gain and associated health conditions.

You may also experience chronic pain as a result of depression. Unexplained aches and pains, like headaches, back pain, or joint tenderness, can be triggered by depression. Although not fully understood, it may be that depression makes you less tolerant of pain, so that everything just hurts more.

Living with depression puts you at risk for serious physical health conditions, including heart disease and stroke. The reason for this may be that depression triggers an overproduction of clotting factors and variation in heart rate. These are both factors that can lead to a heart attack or stroke.

Gastrointestinal distress is a potential complication of depression. The gut actually has a major connection to mood and mental health and is sometimes referred to as the bodys second brain. There are important receptors in the gut and an ecosystem of bacteria, which when out of whack can affect mood. If you are depressed, you may experience stomach aches, indigestion, nausea, cramps, or bloating.

Depressive Disorder: Course Of Illness

What happens in the brain during depression?

The importance of treating this condition cannot be overestimated. The World Health Organization global burden of disease study places unipolar affective disorder amongst the 10 leading medical causes of disability in the world and second only to ischaemic heart disease.

Depression is a highly prevalent psychiatric disorder with a lifetime risk close to 20% and is associated with high levels of morbidity and mortality. Depressed patients are at higher risk of serious physical health problems such as coronary artery disease and diabetes and worsening of the prognosis of other medical conditions.

Follow-up studies show depression to be a long term, relapsing condition associated with significant morbidity and mortality and a tendency towards chronicity. Three quarters of the patients experience more than one episode of depression and the risk of recurrence is higher if the first episode occurs at a younger age and if there is a family history of depression. The risk of recurrence increases with each new episode and as the number of depressive episodes increases, the influence of life stress on recurrence wanes.

Given these findings, the need for effective treatment in the first episode of depression is obvious. Maintenance treatment for several months during remission is essential after an acute episode of depression to prevent relapse as well as long-term treatment to prevent recurrence in patients with more than one episode.

S Of The Brain Are Shrinking

Around the hippocampus are three parts that will shrink when someone has depression. Each of these affects various functions necessary for day-to-day life. These parts are:

  • Thalamus this area controls arousal, emotion, memory, motor function, and physical sensations .
  • Caudate nucleus controls planning the execution of movement, romantic interactions, emotion, learning, memory, and motivation.
  • Insula it controls the sympathetic and parasympathetic systems. These are better known as rest and digest and fight or flight systems. It also regulates the immune system.

What Part Of The Brain Controls Depth Perception

Specifically the part of the brain that does depth perception based on binocular vision. I have searched all over the web and have turned up nothing. Is it the same part of the brain that processes all images from the retina?

This Scientific American article states that there is a process involved:

Visual-image processing from the eye to the brain happens in stages. Rudimentary features such as the orientation of edges, direction of motion, color, and so on are extracted early on in areas called V1 and V2 before reaching the next stages in the visual-processing hierarchy for a progressively more refined analysis. This stage-by-stage description is a caricature many pathways go back from stage to stageallowing the brain to play a kind of 20-questions game to arrive at a solution after successive iterations.

This process is discussed further in this article with what is known as the Laminart model.

Medication And Clinical Assessment

The effect that medication may have on the depressed patients imaging results is still not clear. We reviewed the studies for the proportion of clinically depressed patients on medication in the named studies. Results revealed that in the emotion studies 48% of the depressed participants were medication free, while in the cognitive studies only 13% of the patients were medication-free and 43% were medication free in the resting-state studies. The exact effect of medication on the brain networks of patients diagnosed with depression remains relatively unknown in these samples and this may be significant as a variety of medications were used, including medications classified as serotonin-specific reuptake inhibitors, e.g., paroxetine, medications classified as serotonin and noradrenaline reuptake inhibitors such as venlafaxine, and drugs classified as tri-cyclic antidepressants such as amitriptyline. Unfortunately, the proportion of studies in each of three categories that involved medication-free depressed patients was quite low and did not allow for separate meta-analysis.

Management And Treatment Of Nausea And Vomiting

What Depression and Anxiety Look Like in the Brain
  • Identify the pathway by which each cause triggers the vomiting reflex
  • Identify the chemical transmitter involved in the identified pathway
  • Choose a drug that is able to act as a preventer of this reflex pathway
  • Appropriate drug delivery . The route of administration depends on the state and condition of the patient. Drugs in rectal or parental form are necessary where oral medication is not tolerated or is contraindicated such as after major surgery
  • Try to optimise the dose of the medication .
    • Discuss anti nausea medications with your doctor
    • Avoid eating 12 hours before your treatment if this makes nausea worse. Try to catch up after treatment
    • Avoid foods that:
  • Eat small amounts more frequently and eat slowly
  • Eat before you get hungry, because hunger can make feelings of nausea stronger
  • Avoid eating in a room that is stuffy, too warm, or has cooking odors that might disagree with you
  • Sip cold clear fluids . This is particularly important if you are vomiting to prevent dehydration
  • Have foods and drinks at room temperature or cooler hot foods may add to nausea
  • Rest after meals, because activity may slow digestion. Its best to rest sitting up for about an hour after meals
  • Choose stomach-friendly foods, such as toast, crackers, yoghurt, creamed rice, oatmeal, boiled potatoes, rice, noodles, steamed/baked skinned chicken, canned peaches or other soft, bland fruits and vegetables, carbonated drinks that have gone flat

    The Study Of Human Sadness

    The people who participated in the study were hospital patients awaiting brain surgery for severe epilepsy. Before the medical intervention, a series of wires were inserted inside their heads that recorded their electrical activities over a period of seven days.

    After the week, the scientists were able to observe that certain mood states coincided with the internal communication of specific networks located in the brain, noting that in 13 of the patients there was a link between sadness and a particular neural circuit that connects the amygdala that, in turn, is related to emotional fluctuations and the hippocampus, which helps store memories.

    There was a network that over and over again told us if they were happy or sad, said Vikaas Sohal, a psychiatric academic at the University of California.

    Swallowing Centers In The Brain

    The voluntary initiation of swallowing takes place in special areas of the cerebral cortex of the brain called the precentral gyrus , posterior-inferior gyrus, and the frontal gyrus. Information from these areas converges in the swallowing center in the medulla, which is part of the brainstem.

    Apart from the brain, nerve signals originating in the mouth receive input about the food we are chewing. Several sensory nerves in the mouth, pharynx, and larynx bring information to the brain that allows us to know what type of material is in the mouth and throat. For instance, they tell the brain about the size, temperature, and texture of food.

    This information is sent to the sensory cortex of the brain, and eventually the medulla, which uses the sensory information to direct the efforts of the muscles of chewing.

    What Can Be Done To Control Or Relieve Nausea And Vomiting

    There are several ways to control or relieve nausea however, if these techniques do not seem to ease the queasiness, talk to your doctor.

    When trying to control nausea:

    • Avoid activity after eating.
    • Avoid brushing your teeth after eating.
    • Choose foods from all the food groups as you can tolerate them to get adequate nutrition.

    Treatment for vomiting includes:

    • Drinking gradually larger amounts of clear liquids
    • Avoiding solid food until the vomiting episode has passed
    • Resting
    • Temporarily discontinuing all oral medications, which can irritate the stomach and make vomiting worse

    If vomiting and diarrhea last more than 24 hours, an oral rehydrating solution should be used to prevent and treat dehydration.

    Vomiting associated with surgery, radiation therapy, anticancer drugs, alcohol and morphine can often be treated with another type of drug therapy. There are also prescription and nonprescription drugs that can be used to control vomiting associated with pregnancy, motion sickness and . However, you should consult with your healthcare provider before using these treatments.

    Changing In Brain Parts Causes

    Depression affects a person

    As you can see, those with symptoms of depression have the struggle with shrinking in areas that control important functions for a mundane life. Those symptoms are a reflection of the changes in the brain. They include:

    • Memory problems being forgetful and not having memories are big issues for patients with mood disorders. With fewer brain cells to perform the normal functions, these diminish with it.
    • Trouble thinking clearly if people are struggling with memories, they are also struggling with thinking. For example, someone may forget what they are talking about mid-sentence or struggle to solve a simple problem.
    • Guilt or hopelessness with emotional dysregulation comes guilt and hopelessness. People will often have these emotions outside of normal instances.
    • No motivation when the chemical messengers arent making their way to the inner brain, motivation becomes a problem. This will look like an inability to get out of bed. No desire to go to work. No desire to make a meal.
    • Sleep or appetite problems the shrinking of the thalamus and the insula have a big impact on our ability to sleep and our gastrointestinal system. As a result, depressed people often struggle to fall or stay asleep. As a result, many experience weight loss or weight gain, depending on their reaction.
    • Anxiety patients usually have depression and anxiety together. Between decreased brain function and the stress that comes with it, anxiety disorders are prevalent.

    When Does Anxiety Become Unbearable

    Generalized Anxiety Disorder occurs when going through the day is filled with exaggerated worry when there is little to provoke it. Certainly, on any given day, stressful situations happen that cause brief episodes of angst. But when anxiety becomes pervasive for 6 months or more, it is time to seek treatment.

    S Of The Brain: Structures Anatomy And Functions

    The human brain is one of the largest and most complex organs in the body. It controls your emotions, thoughts, speech, memory, creativity, breathes, movement, and stores information from the outside world. This article discusses the different parts of the brain and the function of each structure.

    The brain is a 3-pound organ that contains more than 100 billion neurons and many specialized areas. There are 3 main parts of the brain include the cerebrum, cerebellum, and brain stem. The Cerebrum can also be divided into 4 lobes: frontal lobes, parietal lobes, temporal lobes, and occipital lobes. The brain stem consists of three major parts: Midbrain, Pons, and Medulla oblongata. Although each structure has a distinct function, they work together to control all functions of the body.

    A Changing Brain: How Depression Can Alter Our Brain Structure

    The Brain & Bipolar Disorder

    Living with Depression | byBlurt Team|

    Weve always known that mental illness and physical illness are intrinsically interlinked and inseparable. As more research is done into depression, researchers are discovering that it can alter our brain structure. Its hoped that research in this area could lead to better treatment and less stigma.

    Residential Treatment Provides A Space To Heal

    One of the most important reasons to choose residential care for depression treatment is that it gives you the space, the time, and the opportunity to truly focus on healing. There are no distractions of home, work, and other responsibilities, only a safe place to get better. The damage that depression has done to your brain and body can be slowed, stopped, and even reversed with good care.

    The most effective treatment for depression is a combination of therapy and medications, both of which take time to work. This is another reason that residential treatment is a smart choice for depression care. It gives you time to develop a rapport with a therapist and to make positive changes. It also gives you a chance to try one or more antidepressants to find the medication that will adjust your brain chemicals in just the right way for maximum impact with fewest side effects.

    Getting relief from depression through treatment will immediately begin to help your brain, reversing the shrinking of certain areas, the inflammation, and the overflow of cortisol. This in turn will help you feel better overall, and you will begin to get relief for the physical symptoms.

    The Hypothalamus Manages Sensory Impulses Controls Emotions And Regulates Internal Functions

    The hypothalamus is part of the diencephalon, a region of the forebrain that connects to the midbrain and the cerebrum. The hypothalamus helps to process sensory impulses of smell, taste, and vision. It manages emotions such as pain and pleasure, aggression and amusement. The hypothalamus is also our visceral control center, regulating the endocrine system and internal functions that sustain the body day to day. It translates nervous system signals into activating or inhibiting hormones that it sends to the pituitary gland. These hormones can activate or inhibit the release of pituitary hormones that target specific glands and tissues in the body. Meanwhile, the hypothalamus manages the autonomic nervous system, devoted to involuntary internal functions. It signals sleep cycles and other circadian rhythms, regulates food consumption, and monitors and adjusts body chemistry and temperature.
