Childhood development has critical periods of development. Development: systematic changes in behaviours and abilities that occur between the moment of conception and death, change: continual and cumulative, effects of one age have ramifications at other ages. Early stages of development: most rapid, crucial periods of development in infants and children. Teratogens: are toxins, anything that has an adverse effect on development, effects range from very mild to death, many are only a problem if exposure occurs during sensitive period. Factors in aging include: telomere shortening, oxidative stress, time (chronological age), and sugars. Diagnostic criteria: dementia: the development of multiple cognitive deficits manifested by both. Memory impairment (impaired ability to learn new information or to recall previously learned information) One (or more) of the following cognitive disturbances. Apraxia (impaired ability to carry out motor activities despite intact motor function) Agnosia (failure to recognize or identify objects despite intact sensory function)
