Help My Brother Return To Life

My name is Tanya, I'm 26. My brother Evgeniy is 32. 5 months ago he was hospitalized in critical condition by emergency team after horrible accident. He was robbed and beaten up to his way home. 31 of May in the evening he called to his wife and said he will be home for 1 hour. He was founded 1 of June in the morning by unknown people in critical condition and was delivered in the reanimation where he situated 3 months and was in coma.
Last 2 months he is in vegetative state. He hears everything and sometimes opens his eyes but clear consciousness is off yet. Complete diagnosis: Severe craniocerebral injury. Severe brain contusion similar to diffuse  axonal injury. Intraventricularhemorrhage.  Contused wound, bruises, head abrasion. Сгush syndrome. Vegetative state, faded tetraplegia, bulbar syndrome. He has a wife and 7 years old son Danil . My brother loves his son more than life and he would give away everything to see how his son grows. He is very good-humoried, kind and positive person who had big plans on his future. We are happy that he has so big progress but reabilitation like massage and special medicines are very expensive. Our mother died 5 years ago in the car accident and now my brother has nobody exсept me could help him. Our family spent all money we had for last months on treatment. I'm full time working mom and all money I get I send on my brother's treatments but it is not enough! Now I am forced to ask you for help! I write this post with tears in my eyes and hope my brother will become healthy again because he is so young!!!
God bless you and your families...
