Answer:
Addiction.
Explanation:
A person with an addiction uses a substance, or engages in a behavior, for which the rewarding effects provide a compelling incentive to repeat the activity, despite detrimental consequences. Addiction may involve the use of substances such as alcohol, inhalants, opioids, cocaine, and nicotine, or behaviors such as gambling.
There is evidence that addictive behaviors share key neurobiological features: They intensely involve brain pathways of reward and reinforcement, which involve the neurotransmitter dopamine. And, in keeping with other highly motivated states, they lead to the pruning of synapses in the prefrontal cortex, home of the brain's highest functions, so that attention is highly focused on cues related to the target substance or activity. It is important to know that such brain changes are reversible after the substance use or behavior is discontinued

Explanation:
Anti-vaccine groups have been identified by the World Health Organization (WHO) as one of the most important global threats against health security. Anti-vaccination is a movement that comes from a controversial belief based on a paper published in a top medical journal (The Lancet). This study suggested that the MMR vaccine (against measles, mumps, and rubella) might be associated with autism spectrum disorders in children. However, in other studies, it has been shown that there is no association between this vaccine and autism, thereby this controversial paper was retracted by the editors of the journal.

Explanation:
Hyperpituitarism is a disease of pituitary gland in which one or more of the hormones produced by the pituitary gland are over secreting causing higher amounts of hormone production. The hormones of the pituitary glands are related to growth, metabolism, sexual maturation and reproductive functions. the medications for hyperthyroidism are given in low titrated doses as per severity of hyperthyroidism. High dose may have higher frequency of side effects. Hence the lower the dose, the lower the risk.
