¿Cómo se diagnostica el TDAH en adultos?
El diagnóstico formal del TDAH en adultos se realiza utilizando la evidencia acumulada de la evaluación clínica inicial y los sistemas de clasificación médica. La evaluación formal y el diagnóstico solo deben ser realizados por profesionales de la salud debidamente calificados, como psiquiatras especialistas, enfermeras especializadas u otros profesionales de la salud calificados, que tengan capacitación y experiencia en el diagnóstico del TDAH.
¿Qué es el TDAH y cómo se trata?
El Trastorno por Déficit de Atención/Hiperactividad (TDAH) puede ser algo que usted ha escuchado y asociado con niños que tienen dificultades para prestar atención, o que son hiperactivos e impulsivos. Sin embargo, los adultos también pueden tener TDAH. De hecho, alrededor del 4-5% de la población adulta en los Estados Unidos lo tiene, aunque los casos de TDAH entre la población adulta son probablemente mucho más altos ya que pocos adultos son diagnosticados o tratados por ello.
¿Qué porcentaje de la poblacion tiene TDAH?
En los Estados Unidos hay una prevalencia del 4.1% de TDAH entre la población adulta. El 41.3% de estos casos se clasifican como graves. De estos adultos con TDAH, el 38% son mujeres y el 62% son hombres. La prevalencia mundial de TDAH en adultos es del 3.4%.
¿Cómo tratar el TDAH?
Intervenciones no farmacológicas: Esto puede incluir la psicoeducación mediante la cual los pacientes y las familias reciben educación sobre el TDAH de forma individual o como parte de sesiones de educación grupal. Esto enseña a los receptores a ser más conscientes de los síntomas del TDAH y cómo proporcionar un apoyo adecuado. Las intervenciones no farmacológicas también pueden incluir terapia cognitiva de conducta para ayudar a los pacientes a reconocer patrones de comportamiento disruptivo y enseñarles cómo manejarlo mejor.

How is TDA manufactured?
TDA is manufactured by nitrating toluene to produce dinitrotoluene, which is then catalytically reduced to TDA. TDA is a colorless solid that tends to darken on storage and exposure to air. Other chemical and physical properties of 2,4-TDA are listed in Table 1.
What is the purpose of the TDA bulletin?
The purpose of this bulletin is to disseminate recent information on the potential carcinogenicity of toluene diisocyanate (TDI) and toluenediamine (TDA) to humans . Recent studies of chronic effects in animals have produced evidence that cancer is associated with exposure to commercial-grade TDI (an 80:20 mixture of 2,4- and 2,6-TDI) and to 2,4-TDA, a hydrolysis product of TDI. This bulletin describes the results and implications of those animal studies, presents the known human health effects of TDI and TDA, and suggests guidelines for minimizing occupational exposures.
How is TDA exposed to the environment?
Workers may be exposed to TDA by dermal contact and, less frequently, by inhalation. Although solid TDA does not normally present an inhalation hazard, it may also be handled and shipped in the molten state, at which time the vapors may present a hazard. An estimated 8,513 workers were exposed to TDA in the United States (luring the period 1981 to 1923 [ NIOSH 1983 ]. Potential for worker exposure is minimal because more than 99% of the TDA produced is used captively to produce TDI, usually at the same site [ NTP 1985 ]. During the manufacture of TDA, TDA concentrations have ranged from 0.0002 to 0.1241 parts of TDA per million parts (ppm) of air, or 0.001 to 0.620 milligrams per cubic meter (mg/m 3) [ Ahrenholz and Meyer 1980, 1982 ].
What is TDI made of?
TDI is manufactured by the reaction of TDA with carbonyl chloride (phosgene). TDI is a colorless-to-amber liquid with a pungent odor. Commercial-grade TDI (which represents more than 95% of TDI industrial usage) is an 80:20 mixture of the two chemical isomers 2,4- and 2,6-TDI.
What is the maximum exposure limit for TDI?
The current OSHA permissible exposure limit (PEL) for TDI is 0.005 ppm (0.04 mg/m 3) as an 8-hr time-weighted average (TWA) concentration and 0.02 ppm (0.15 mg/m 3) as a short-term exposure limit (STEL) for any 15-minute period [54 FR * 2,662 (1989)]. In two separate criteria documents, NIOSH has recommended that exposure to TDI be limited to 0.005 ppm (0.036 mg/m 3 **) as a TWA concentration for up to a 10-hour workday and a 40-hour workweek, with a ceiling concentration of 0.02 ppm (0.14 mg/m 3) for any 10-minute period [ NIOSH 1973, 1978 ]. The NIOSH recommended exposure limit (REL) was intended to prevent acute and chronic irritation and sensitization of workers but not to prevent responses in workers who are already sensitized. Available data do not indicate a concentration at which TDI vapor fails to produce adverse reactions in sensitized persons. The American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit value (TLV ®) for TDI is 0.005 ppm (0.04 mg/m 3) as an 8-hour TWA concentration and 0.02 ppm (0.15 mg/m 3) as a STEL [ ACGIH 1988 ]. No occupational exposure limit for TDA has been established by OSHA, NIOSH, or ACGIH.
How many workers were exposed to TDA?
An estimated 8,513 workers were exposed to TDA in the United States (luring the period 1981 to 1923 [ NIOSH 1983 ]. Potential for worker exposure is minimal because more than 99% of the TDA produced is used captively to produce TDI, usually at the same site [ NTP 1985 ].
How much TDI was produced in 1986?
In 1986, 650 million pounds of TDI were produced in the United States, and the demand is expected to rise in the future [ American Chemical Society 1987 ]. TDI is widely used in the manufacture of flexible polyurethane foams, elastomers, surface coatings, fibers, sealants, and adhesives.
