You can add this functionality in your point.mouseOver and point.mouseOut events callback functions.

You can use point.graphic.shadow() for adding shadow to your point and then remove this shadow manually on mouseOut.

Here you can see code that may help you:

   point: {
      events: {
        mouseOver: function() {
          this.graphic.shadow({
            width: 10
          })
        },
        mouseOut: function() {
          Highcharts.each(this.graphic.shadows, function(p) {
            p.remove();
          })
        }
      }
    }
