how to break in middleware in expressjs

I have a MEAN stack based web application and I have a middle ware which validates the request for some authorization purpose. I have written the security checking part but if the user is unauthorized, the express middle ware should stop execution and return back user 401 status with a message. How can I achieve it? I tried to to use return statement in middle ware but it is not working. Though some of them works, it throws an exception and breaks the server. I want just an abrupt ending to the request. Any help will be appreciated.

Assuming that isValid is a hypothetical function to check the validity of the request. 

function authMiddleware(req,res,next){
  if(isValid(req)){
   next(); // calls the next middleware
  }else {
   return res.sendStatus(401); // sends HTTP 401 back
  }
}
