Does mood state change risk taking

Share via Email Something very strange happens at puberty, when truckloads of hormones begin arriving by the day. Children who were once sweet, helpful and good fun to be around turn, almost overnight, into grunting creatures, who wear nothing but black, lie abed until noon and consume 5,calorie snacks followed immediately by saying that they are still hungry. They are spotty, frequently smelly, and grow out of every item of clothing they have in the space of a few months.

Beyond raging hormones Published: March, Originally published in the Harvard Mental Health LetterJuly In every generation, it seems, the same lament goes forth from the parents of adolescents: Accidental deaths, homicides, and binge drinking spike in the teenage years. It's the time of life when psychosis, eating disorders, and addictions are most likely to take hold.

Surveys show that everyday unhappiness also reaches its peak in late adolescence. Plenty of explanations for teenage turmoil are available. Adolescents need to assert their independence and explore their limits, taking risks, breaking rules, and rebelling against their parents while still relying on them for support and protection.

Cultural change heightens incompatibility between the generations. Now scientific research is suggesting a new reason for the clashes between teenagers and their environment. Unsettled moods and unsettling behavior may be rooted in uneven brain development. It's not a question of intellectual maturity.

Most studies show that abstract reasoning, memory, and the formal capacity for planning are fully developed by age 15 or If teenagers are asked hypothetical questions about risk and reward, they usually give the same answers as adults.

But the emotional state in which they answer questionnaires is not necessarily the one in which they make important choices. In real life, adolescents, compared to adults, find it more difficult to interrupt an action under way stop speeding ; to think before acting learn how deep the water is before you dive ; and even to choose between safer and riskier alternatives.

It is easy for them to say that they would not get into a car with a drunk driver, but more difficult to turn down the invitation in practice. Adolescents' judgment can be overwhelmed by the urge for new experiences, thrill-seeking, and sexual and aggressive impulses.

Are you an older adult with depression?

They sometimes seem driven to seek experiences that produce strong feelings and sensations. Resisting social pressure is also more difficult for teenagers.

Much of their troubling behavior, from gang violence to reckless driving and drinking, occurs in groups and because of group pressure. In a psychological experiment, adolescents and adults took a driving simulation test that allowed them to win a reward by running a yellow light and stopping before they hit a wall.

Adolescents, but not adults, were more likely to take extra chances when friends were watching. Another revealing psychological experiment is the Iowa gambling task. Subjects can choose from one of two decks of cards in the hope of picking a card that provides a reward.

The "good" deck contains many cards that provide some reward; the "bad" one, many cards that provide nothing and insufficient compensation in the form of a few that hold a jackpot. The choices of adults correspond fairly well to their tested reasoning capacity.

In adolescence, the correlation is much weaker. Evidence is appearing that these differences have a definite basis in brain structure and functioning.

Recent research has shown that human brain circuitry is not mature until the early 20s some would add, "if ever". Among the last connections to be fully established are the links between the prefrontal cortex, seat of judgment and problem-solving, and the emotional centers in the limbic system, especially the amygdala.

These links are critical for emotional learning and high-level self-regulation. Beginning at puberty, the brain is reshaped. Neurons gray matter and synapses junctions between neurons proliferate in the cerebral cortex and are then gradually pruned throughout adolescence.

Meanwhile, the white insulating coat of myelin on the axons that carry signals between nerve cells continues to accumulate, gradually improving the precision and efficiency of neuronal communication — a process not completed until the early 20s.

The corpus callosum, which connects the right and left hemispheres of the brain, consists mostly of this white matter. Another circuit still under construction in adolescence links the prefrontal cortex to the midbrain reward system, where addictive drugs and romantic love exert their powers.

Most addictions get their start in adolescence, and there is evidence that adolescent and adult brains respond differently to drugs. In both human beings and laboratory rats, studies have found that adolescents become addicted to nicotine faster and at lower doses.

Functional brain scans also suggest that teenagers and adults process reward stimuli differently; the adolescents are hypersensitive to the value of novel experiences.Carbamazepine (Tegretol) is an effective mood stabilizer for bipolar disorder, but it seems that the 10/11 epoxide metabolite is responsible for some of the major problems that can occur with the drug.

Chapter 5 — Mood Disorders Definitions and Diagnoses The term mood describes a pervasive and sustained emotional state that may affect all aspects of an individual’s life and perceptions. Mood disorders are pathologically elevated or depressed disturbances of mood, and include full or partial episodes of depression or mania.

Depression, mood, and sex. The relationship between sexuality and depression or mood state is often complicated. Depression can be both a cause and a result of a sexual problem. No study has been conducted to evaluate the influences of age differences on specific moods for risk.
