   Understanding the differences with strokes in CADASIL    
      
   Small Vessel Disease/Lacunar Infarction   
   Small vessel disease, or lacunar infarction, occurs when blood flow is blocked   
   to a very small arterial vessel. The term's origin is from the Latin word   
   lacuna which means hole.   
      
   Patients with CADASIL - if they have strokes, they have the small vessel type   
   of  stroke (only 20% of overall strokes are due to small vessel occlusion and   
   CADASIL  type of stroke falls into this category)  - a small artery closes on   
   its own, not    
   necessarily due to a clot.   
      
      
      
       
      
   Transient Ischemic Attacks (TIA) (sometimes called a mini-stroke)   
   Starts just like a stroke but then resolves leaving no noticeable symptoms or   
   deficits. The addition of other risk factors compounds a person's risk for a   
   recurrent stroke. The average duration of a TIA is a few minutes. For almost   
   all TIAs, the symptoms    
   go away within an hour. There is no way to tell whether symptoms will be just   
   a TIA or persist and lead to death or disability. The patient should assume   
   that all stroke symptoms signal an emergency and should not wait to see if   
   they go away.   
      
   NOTE: It does not mean patients with CADASIL can not have also large vessel   
   disease - carotid artery plaque or cardioembolic type of stroke - when a blood   
   clot forms in carotid artery plaque or the heart, goes to the brain and plugs   
   a vessel deeper in    
   the brain.   
      
   Even though a stroke occurs in the unseen reaches of the brain, the symptoms   
   of a stroke are easy to spot. They include sudden numbness or weakness,   
   especially on one side of the body; sudden confusion or trouble speaking or   
   understanding speech; sudden    
   trouble seeing in one or both eyes; sudden trouble walking, dizziness, or loss   
   of balance or coordination; or sudden severe headache with no known cause. All   
   of the symptoms of stroke appear suddenly, and often there is more than one   
   symptom at the same    
   time. Therefore strokes can usually be distinguished from other causes of   
   dizziness or headache. These symptoms may indicate that a stroke has occurred   
   and that medical attention is needed immediately.
