and it is mainly in this period of the cerebellum

0:10

that we see

0:12

underdevelopment

0:13

now that’s rather interesting because studies now have shown

0:18

that family members of people who have a dat

0:21

eighty eight he was in my family

0:24

that when we look at the parents and that the siblings of people with eighty

wees all socio ndr development in most of these regions

0:33

but not in all of them

0:35

which means that this underdevelopment is part of the family scene a tight

c_d_h_ dat dat is a spectrum disorder

0:42

and biological relatives of affected patients do shows some

0:47

symptoms of a d_h_ d but not the full disorder this is very much like autistic

0:51

spectrum disorders in that sense

0:53

where we see elements

symptoms but not full disorder or diagnose the bull disorder in those

1:25

the affected patients

1:27

have the underdevelopment in the cerebellum

1:29

the non affected family members do not

structure in explaining

why the disorder rises to full disorder
