How Does Depression Affect The Nervous System – To understand mental disorders, it is important to have an understanding of the normal structure and function of the nervous system.

Knowledge of the normal structure and function of the nervous system is key to understanding psychiatric disorders such as major depressive disorder (MDD). This slideshow contains key components of neurosynaptic transmission, neurotransmitters, and hypotheses about the causes of depression. The common genetic basis and environmental factors for MDD are briefly explored.

How Does Depression Affect The Nervous System

To understand mental disorders, it is important to have an understanding of the normal structure and function of the nervous system. The central nervous system (CNS; brain, spinal cord) and the peripheral nervous system (PNS) are made up of neurons…

Neurons are functional units of the nervous system; there are more than 100 billion neurons in the brain.

The brain is divided into four anatomical regions: diencephalon, brainstem, cerebrum, and cerebellum, as explained in the slide.

The cerebral cortex is the main functional unit of the cerebrum. The three main functional areas of the cerebral cortex are:

The brain can be imagined to consist of five ‘lobes’ – four lobes of the cerebral cortex and the fifth lobe, the insula, deep in the brain, as shown in the slide.

Information flows through the nervous system through two integrated forms of communication: electrical neurotransmission and chemical neurotransmission, as shown in the slide.

Neurons do not physically touch each other; two neurons are separated by a gap, known as a synaptic cleft.

The idea that neurotransmission occurs at synapses and is mediated by chemicals was initially a controversial topic.

You may even lose your appetite completely or not eat the right amount of nutritious food. A sudden loss of interest in eating in older adults can lead to a condition called geriatric anorexia.

Brain scans of depressed people show significant changes in brain areas such as the frontal lobe, hippocampus, temporal lobe and amygdala.

It is not surprising that when someone has been diagnosed with heart disease, cancer, or other physical conditions that are life-limiting or life-threatening, they become anxious or depressed. But the opposite can also be true: Excessive anxiety or depression can promote the development of a serious physical illness and even hinder the ability to resist or recover from one. The potential consequences are especially timely as the stress and disruptions of the pandemic continue to affect mental health.

The Link Between Dopamine And Depression

The human organism does not recognize the artificial separation between mental and physical illness in the medical profession. Rather, body and mind are a two-way street. What happens in someone’s head can have harmful consequences for the whole body, but also vice versa. Untreated mental illness can significantly increase the risk of becoming physically ill, and physical disorders can lead to behaviors that lead to mental illness.

In a study investigating how breast cancer patients fared, Dr. David Spiegel and his colleagues at Stanford University School of Medicine observed several decades ago that depressed women live longer than severely depressed women. His research and other studies clearly show that “the brain is closely connected to the body and the body to the brain,” said Dr. Spiegel in an interview. “The body tends to respond to mental stress as if it were physical stress.”

Despite such evidence, she and other experts say, chronic emotional distress is too often overlooked by doctors. Usually, doctors will prescribe therapy for physical conditions such as
