The training protocol is based on the principles of applied behavior analysis. [3] The goal of PECS is spontaneous and functional communication. [3] The PECS teaching protocol is based on B. F. Skinner's book, Verbal Behavior, such that functional verbal operants are systematically taught using prompting and reinforcement strategies that will lead to independent communication.
Alzheimer's disease is the most common form of dementia, which approximately two thirds of individuals with dementia are diagnosed with. [7] It is the major cause of dementia in older adults. [ 8 ] AD has an insidious onset with worsening prognosis, and results in deterioration in memory, spatial abilities, language, and many other cognitive ...
Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF).
This reflex occurs in slightly older infants (starts between 6 and 7 months [24] and become fully mature by 1 year of age) when the child is held upright and the baby's body is rotated quickly to face forward (as in falling). The baby will extend their arms forward as if to break a fall, even though this reflex appears long before the baby walks.
Frontotemporal dementia (FTD) is an early onset disorder that mostly occurs between the ages of 45 and 65, [13] but can begin earlier, and in 20–25% of cases onset is later. [11] [14] Men and women appear to be equally affected. [15] It is the most common early presenting dementia. [16]
By 2030, older people are expected to outnumber children under age 10-14 (1 billion vs. 1.35 billion) and eventually outnumber the number of adolescents and youth globally. Furthermore, the number of persons age 80 years or over is projected to increase more than threefold by 2050, climbing from 127 million to 425 million.
Research suggests that this inability to distinguish between past confabulatory and real events is centered on developmental differences in source monitoring. Due to underdeveloped encoding and critical reasoning skills, children's ability to distinguish real memories from false memories may be impaired.
Dementia with Lewy bodies (DLB) is a type of dementia, a group of diseases involving progressive neurodegeneration of the central nervous system. [11] It is one of the two Lewy body dementias, along with Parkinson's disease dementia. [12] Dementia with Lewy bodies can be classified in other ways.
