NORMAL LEVEL-TWO ULTRASOUND SCAN Ultrasound examination during should include a systematic evaluation of fetal anatomy. Apart from anencephaly‚ the fetal organs cannot be accurately measured before 17-18 weeks of gestation. After 30-35 weeks‚ evaluation becomes increasingly difficult. Hence level-two ultrasound scan is done at 18 to 20 weeks of gestation. CLASSIFICATION OF FETAL SONOGRAPHIC EXAMINATIONS 1. First-Trimester Ultrasound 2. Standard Second- or Third-Trimester Ultrasound

Blood sugar levels and dementia: how our diet could be leading to memory impairment Dementia and memory loss is of major concern for all of us. It is estimated that 35 million people worldwide suffer from Alzheimer’s disease and it has been proposed that this number will grow to around 100 million within the next thirty years (Copped’e‚ 2012).

However‚ there are numerous underlying conditions that
