A reservoir host can harbour a pathogen indefinitely with no ill effects, with important implications for disease control. A single reservoir host may be reinfected several times. A host of predilection is the one preferred by a parasite. An amplifying host is one in which the level of pathogen can become high enough that a vector such as a mosquito that feeds on it will probably become infectious.
Trends in the rates of treatment for ADHD were presented by age, gender, race, family income, and health insurance status. Trends in ADHD treatment were also determined by annual numbers of visits, use of pharmacotherapies, and types of health care professionals. RESULTS: The rate of outpatient treatment for ADHD increased from 0.9 per 100 children in 1987 to 3.4 per 100 children in 1997.
Some doctors think ADHD sufferers are self-medicating with pot to manage their impulsiveness. Interestingly, the latest study found men with ADHD were using pot to help with attention while females with ADHD used it for sleep. ADHD is usually treated by mainstream physicians with stimulants, (i.e. speed). Common side effects of speed include: loss of appetite, sleep problems, and mood swings. The new study published in the journal Psychiatry Research this September, assessed 56 men and 20 women with ADHD ages 18 to 45. âModerate to strong correlations were found between marijuana use and inattentive symptoms in men, and marijuana use and decreased sleep quality in women.
