Hyperactivity symptoms, mania

Comorbid conditions must be addressed in order to maximize desired outcomes. For comorbid bipolar disorder and attention-deficit/hyperactivity disorder when stimulant therapy is indicated, treatment of mania is recommended before starting the stimulant in order to avoid exacerbation of mood symptoms by the stimulant. 

There are two studies of hospitalized children with mania or manic symptoms. The first, a controlled trial of lithium in 11 children (7 of whom were treated under double-blind, placebo-controlled conditions), found that 6 showed improvement over an 8-week period of hospitalization, but only 3 were well enough to be discharged on lithium. Long-standing concurrent ADHD complicated assessment of response (Carlson et al., 1992a), and the addition of methylphenidate was necessary to achieve an improvement in attention span and hyperactivity (Carlson et ah, 1992b). An open trial of lithium in 10 acutely manic/psychotic prepubertal children showed positive response in all (Varanka et ah, 1988). 

Bipolar disorder is characterized by episodes of mania or hypomania, which include hyperactivity, decreased need for sleep, and a euphoric or irritable mood. Additionally, persons with bipolar disorder may have episodes of depression similar to those seen in major depressive disorder. The lifetime prevalence of severe bipolar disorder is about 1% and 3-5% if milder cases are included, afflicting men and women equally. Both bipolar disorder and major depressive disorder tend to be episodic, and in the periods of time between episodes, persons may experience few or no symptoms. The etiology of bipolar disorder is predominately genetic, with a 70% concordance in monozygotic twins. The neurobiology of bipolar disorder is less well understood, and few animal models have been developed. Treatment of bipolar disorder usually involves mood stabilizer medications, including lithium, and the anticonvulsants valproate and carbamazepine. At times, antidepressant and antipsychotic medications are also used. 

Overexcitement of the central nervous system, commonly results in mania, a collective term for symptoms that include frenzied or hyperactivity, lack of concentration, and irrational thoughts and behavior. Anxiety is also associated with overexcitement of the CNS, which greatly effects ones ability to function normally. The neurobiology and control of anxious states has been extensive reviewed 51). 

Several medical, medication-induced, or substance-related causes of mania and depression have been identified (see Table 68-2 for causes of mania and Table 67-1 in Chap. 67 on depressive disorders for causes of depression). " A complete medical, psychiatric, and medication history physical examination and laboratory testing are necessary to rule out any organic causes of mania or depression. An accurate diagnosis is important because some psychiatric and neurologic disorders present with manic-like symptoms. For example, attention-deficit/hyperactivity disorder and a manic episode have similar characteristics thus individuals with bipolar disorder may be misdiagnosed and prescribed central nervous system stimulants. Use of any substance that affects the central nervous system (e.g., alcohol, antidepressants, caffeine, central nervous system stimulants, hallucinogens, or marijuana) can worsen symptoms and decrease the... 

Pb(CH3)4 is absorbed through the skin, the mucosa of the alimentary tract, and the alveoli. Being lipid soluble it is concentrated in the brain, body fat, and liver. Manifestations of poisoning are dominated by involvement of the central nervous system [22] see also [41, 53, 66, 95, 98, 99]. Symptoms of Pb(CH3)4 as well as of Pb(C2H5)4 intoxication include insomnia, excessive dreaming, toxic psychosis, headaches, hyperactivity, ataxia, emotional instability, erratic behavior, delusions, convulsions, and mania [66, 100]. However, there is also a case reported with a patient showing no such symptoms [50]. Hematological abnormalities are rarely observed [66].
