When depression is treated, you can reverse the damage. With successful treatment, brain scans will likely show you an average, healthy brain.
Each person's recovery is different. Some recover in a few weeks or months. But for others, depression is a long-term illness. In about 20% to 30% of people who have an episode of depression, the symptoms don't entirely go away.
Research published in CNS Neuroscience & Therapeutics found that strength training, aerobic activity, and mind-body exercise, such as yoga, can reduce depressive symptoms and induce neuroplasticity—the brain's ability to repair itself.
Depression is correlated with atrophy of neurons in the cortical and limbic brain regions that control mood and emotion. Antidepressant therapy can exhibit effects on neuroplasticity and reverse the neuroanatomical changes found in depressed patients.
Scientists now know that the brain has an amazing ability to change and heal itself in response to mental experience. This phenomenon, known as neuroplasticity, is considered to be one of the most important developments in modern science for our understanding of the brain.
Brain fog can be caused by anxiety, depression, and other medical conditions. Prolonged cognitive decline can create difficulties with daily functioning, working, and schooling. Hormonal changes and brain inflammation can increase brain fog symptoms.
Depression causes the hippocampus to raise its cortisol levels, impeding the development of neurons in your brain. The shrinkage of brain circuits is closely connected to the reduction of the affected part's function. While other cerebral areas shrink due to high levels of cortisol, the amygdala enlarges.
Research has shown that memory loss is a side effect of depression. Thankfully, it may be reversed with the help of revolutionary medical treatments like therapeutic molecules.
It is possible to recover from mental health problems, and many people do – especially after accessing support. Your symptoms may return from time to time, but when you've discovered which self-care techniques and treatments work best for you, you're more likely to feel confident in managing them.
You may be diagnosed with mild, moderate or severe depression. Your mental health professional may diagnose you with depression if these symptoms: happen most days. last for at least two weeks.
Ongoing depression likely causes long-term changes to the brain, especially in the hippocampus. That might be why depression is so hard to treat in some people. But researchers also found less gray matter volume in people who were diagnosed with lifelong major depressive disorder but hadn't had depression in years.
People who are depressed cannot simply “pull themselves together” and be cured. Without proper treatment, including antidepressants and/or psychotherapy, untreated clinical depression can last for weeks, months, or years. Appropriate treatment, however, can help most people with depression.
Luckily, the plasticity of the brain allows it to mold, change, and rebuild damaged areas as you practice new behaviors. So implementing healthy stress-relieving techniques can train your brain to handle stress more effectively and decrease the likelihood of ill effects from stress in the future.
Some believe it is unlikely that antidepressants cause any permanent changes to brain chemistry in the long term. The evidence seems to indicate that these medications cause brain changes that only persist while the medication is being taken or in the weeks following withdrawal.
The serotonin hypothesis says that depression is caused by not enough of a chemical messenger called serotonin in the brain. A related idea is that brain chemicals are out of balance.
There's no cure for mental illness, but there are lots of effective treatments. People with mental illnesses can recover and live long and healthy lives.
Many of us have had the thought, “I feel like I'm losing my mind” at one time or another. This thought may surface in times of heightened stress, but it can also be a manifestation of a mental health condition, such as anxiety,1 panic disorder,2 or depersonalization.
Recent studies suggest that the increased level of stress associated with depression may raise levels of glucocorticoid. This steroid can have harmful effects on the nervous system, damaging a region of the brain called the hippocampus that is crucial to creating long-term memories.
In neurophysiology, long-term depression (LTD) is an activity-dependent reduction in the efficacy of neuronal synapses lasting hours or longer following a long patterned stimulus. LTD occurs in many areas of the CNS with varying mechanisms depending upon brain region and developmental progress.
Therapies that focus on cognitive functioning, such as cognitive remediation and neurorehabilitation programs, may also help reduce brain fog symptoms. Some people may also find home remedies and lifestyle choices that improve cognitive skills beneficial.
