Physiological psychologists study behavioral phenomena that can be observed in nonhuman animals. They attempt to understand the physiology of behavior: the role of the nervous system, interacting with the rest of the body (especially the endocrine system, which secretes hormones), in controlling behavior.

The Physiological Basis of Behaviour deals with the basic structures of the central nervous system, the techniques used in neuroscience and examnines how drugs affect the brain.

Physiological psychology studies many topics relating to the body’s response to a behavior or activity in an organism. It concerns the brain cells, structures, components, and chemical interactions that are involved in order to produce actions.

Sees behavior and mental processes in terms of their genetic adaptations for survival and reproduction. Humanistic. Emphasizing human ability growth potential and free will. Psychodynamic.

Activities which affect organs and systemic functions without regard to a particular disease.

Abstract. Physiological changes occur with aging in all organ systems. The cardiac output decreases, blood pressure increases and arteriosclerosis develops. The lungs show impaired gas exchange, a decrease in vital capacity and slower expiratory flow rates.

The definition of physiological is the normal functions of a living thing. An example of physiological is a person shedding skin. Characteristic of or promoting normal, or healthy, functioning.

The best treatment option for many people who struggle with disorders is psychotherapy. Several forms of psychotherapy — cognitive therapy, behavioral therapy, interpersonal therapy, and psychodynamic therapy — have been found to successfully treat many disorders, including disorders with severe symptoms.

Inheriting Mental Disorders

• Depression – Affects 10% of the population.
• Attention Deficit-Hyperactivity Disorder (ADHD) – Affects 5%-11% of the population.
• Autism Spectrum Disorder (ASD) – Affects 1 in 68 children.
• Substance use disorders (addiction) – Affects 10% of the population.
• Schizophrenia – Affects 1% of the population.

Four of the main types are:

• Single-gene inheritance diseases.
• Multifactorial genetic inheritance disorders.
• Chromosome abnormalities.
• Mitochondrial genetic inheritance disorders.

According to the Journal of Molecular Medicine, Ribose-5 phosphate isomerase deficiency, or RPI Deficinecy, is the rarest disease in the world with MRI and DNA analysis providing only one case in history.

Sickle cell disease is the most common inherited blood disorder in the United States, affecting around 100,000 Americans, most commonly in African Americans. There is a 25% chance that a child will be born with sickle cell disease if both parents have the defective gene.

Many genetic disorders result from gene changes that are present in essentially every cell in the body. As a result, these disorders often affect many body systems, and most cannot be cured. However, approaches may be available to treat or manage some of the associated signs and symptoms.

This means the common traits or characteristics or even diseases can pass on to an individual at the time of birth from his parents. Genetic disorders are not curable but can only be prevented. Genetic disorder is one of several cause of infant mortality.

Genetic disorders can be caused by a mutation in one gene (monogenic disorder), by mutations in multiple genes (multifactorial inheritance disorder), by a combination of gene mutations and environmental factors, or by damage to chromosomes (changes in the number or structure of entire chromosomes, the structures that …

Some people inherit genetic disorders from the parents, while acquired changes or mutations in a preexisting gene or group of genes cause other genetic diseases.

There are well over 6,000 known genetic disorders, and new genetic disorders are constantly being described in medical literature. More than 600 of these disorders are treatable. Around 1 in 50 people are affected by a known single-gene disorder, while around 1 in 263 are affected by a chromosomal disorder.
