This video discusses sickle cell anemia, the most common inherited disorder worldwide and rapidly increasing in the UK. It is characterized by abnormal hemoglobin in red blood cells, leading to sickle-shaped cells that poorly carry oxygen. This video condition can result in cognitive challenges, especially in processing speed and executive functions. Research is being conducted to improve hemoglobin levels and understand mechanisms that could enhance cognitive outcomes.

A study conducted from 2005 to 2014, with follow-ups in 2017 and 2019, investigated the relationship between changes in hemoglobin and cognitive abilities in black British children with severe sickle cell disease. The findings revealed a significant association between hemoglobin levels and processing speed, suggesting that oxygen supply to the brain impacts cognition. The study emphasized that hemoglobin can affect both organ damage and cognitive capabilities.

It calls for further longitudinal studies to affirm cognition as a crucial endpoint in clinical trials, recommending the incorporation of cognitive assessments to evaluate treatment effectiveness comprehensively.

00:00.000 --> 00:03.285
Sickle cell anemia is the most common inherited disorder

00:03.565 --> 00:06.365
globally and the fastest growing in the uk.

00:07.225 --> 00:10.365
It affects hemoglobin in red blood cells causing them

00:10.385 --> 00:13.165
to become sickle shaped and poor oxygen carriers.

00:13.715 --> 00:15.405
This can lead to cognitive challenges,

00:15.405 --> 00:18.765
particularly in processing speed and executive functions.

00:19.845 --> 00:21.245
Researchers are investigating ways

00:21.465 --> 00:22.925
to improve hemoglobin levels

00:23.505 --> 00:25.565
and understand the underlying mechanisms

00:25.665 --> 00:27.285
to enhance cognitive outcomes.

00:27.635 --> 00:30.045
This study aimed to investigate the relationship

00:30.045 --> 00:31.565
between hemoglobin changes

00:32.025 --> 00:33.445
and cognition in children

00:33.445 --> 00:34.965
with sickle cell disease over time.

00:37.065 --> 00:40.245
It collected data from 2005 to 2014

00:40.785 --> 00:43.805
and followed up in 20 17, 20 19,

00:44.515 --> 00:47.005
looking at multiple hemoglobin measurements

00:47.185 --> 00:50.445
and cognitive data from children identified as black British

00:50.955 --> 00:52.605
with the severe form of sickle cell.

00:52.905 --> 00:55.525
The research aimed to improve understanding of

00:55.545 --> 00:58.965
how blood transfusions affect cognitive abilities in

00:59.245 --> 01:00.565
patients with sickle cell disease.

01:01.745 --> 01:04.405
The study found that processing speed was significantly

01:04.615 --> 01:08.485
associated with hemoglobin, indicating that oxygen supply

01:08.505 --> 01:10.205
to the brain affects cognition.

01:10.695 --> 01:13.925
Hemoglobin has multiple effects including improving organ

01:13.945 --> 01:15.765
damage and cognitive functions.

01:17.195 --> 01:19.765
Further longitudinal investigations are needed

01:19.825 --> 01:23.045
to establish cognition as an endpoint in clinical trials.

01:23.675 --> 01:27.445
Incorporating cognitive tests into clinical trials would

01:27.445 --> 01:29.285
provide a more comprehensive understanding

01:29.465 --> 01:30.725
of treatment effectiveness.
