the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form  

example: i am studying at this moment .

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.

first aid for seizures is aimed at keeping the person safe until the seizure stops on its own. stay calm, loosen anything around the person's neck, do not restrain them or put anything in their mouth, clear the area around them, and stay with them after the seizure stops.

hope this !
