The cognitive deficit is an impairment to one or more of the processes, for example:….. resulting in a lose of efficiency or reduction of function.
B.比较基本水平的问题是不能充分地注意，对 简单刺激有反应如声音或物体(在恢复早期更 常见)
can be at a more basic level where a person is unable to adequately attend and respond to simple stimuli, such as sounds or objects (more often seen in the early stages of recovery)

C.较高级水平的注意问题包括不能把注意力从一 件事上转到另一件事上，或分别注意同时发生的 两件事情上。
higher level of attention problems include the inability to shift attention from one task to another or divided attention between two simultaneous occurring events .
注意力代表了基本的思维水平，这个过程的破坏对其他认知领域有负 面影响

脑损伤后常见认知障碍表现
Description of cognitive impairment commonly
一般说来，脑损伤后认知障碍常见有6个 方面。
In general, there are six broad areas of cognition commonly impaired following brain injury:
•capacity to concentrate on a continuous task •attention span/vigilance
Divided & alternating concentration
capacity to respond on two or more tasks simultaneously (divided attention, mental tracking)
初级记忆Primary memory
For temporary, passive storage of information
information is held in conscious awareness (Immediate memory)
assess by digit span (5-7 chunks)
• capacity to move flexibly between tasks (alternating,shifting attention)
