Sudden Stop in Movements
If a person unexpectedly stops while moving and does not respond to you, then he or she might be having an absence seizure. In most cases, the condition lasts only 15 seconds or more. These people tend to become partially or completely non-responsive and blank out. After this period, they would return to the normal state and do not remember anything about the previous one. This is one of the most obvious signs that the seizure is affecting their memory functions. [2]
