If a person has difficulty with specific types of concepts, for example spatial terms, such as over, under, here and there, they may also have difficulties with arithmetic, understanding word problems and instructions, or difficulties using words at all. They may also have a more general problem with words or sentences, both comprehension and orally. Some children will have issues with pragmatics – the use of language in social contexts as well; and therefore, will have difficulty with inferring meaning. Furthermore, they have severe impairment of spontaneous language production and for this reason, they have difficulty in formulating questions. Generally, children will have trouble with morphosyntax, which is word inflections. These children have difficulty understanding and applying grammatical rules, such as endings that mark verb tenses (e.g. -ed), third-person singular verbs (e.g. I think, he thinks), plurals (e.g. -s), auxiliary verbs that denote tenses (e.g. was running, is running), and with determiners (the, a). Moreover, children with mixed receptive-expressive language disorders have deficits in completing two cognitive operations at the same time and learning new words or morphemes under time pressure or when processing demands are high. These children also have auditory processing deficits in which they process auditory information at a slower rate and as a result, require more time for processing. Presentation

Studies show that low receptive and expressive language at young ages was correlated to increased autism symptom severity in children in their early school years. Below is a chart depicting language deficits of children on the autistic spectrum.
Greek-Cypriot model Sophia Hadjipanteli is also known for her unibrow.It is also the trademark of NBA player Anthony Davis, football player Marouane Fellaini and YouTuber ElectroBOOM. Famous boxer Roberto Elizondo also famously sported a unibrow during his professional boxing fighting days.Bert, Herry Monster, and Oscar the Grouch from Sesame Street, Muppets Sam Eagle, Statler and Animal, Tim Lockwood from Cloudy with a Chance of Meatballs, Spanky Ham from Drawn Together, Squilliam Fancyson from SpongeBob SquarePants, Helga Pataki from Hey Arnold!, and Baby Gerald from The Simpsons are fictional characters with a unibrow. Medicine
Genetics
The unibrow is a genetic trait. It is associated with the PAX3 gene. Medical conditions
A unibrow is part of normal human variation, but can also stem from developmental disorders. A unibrow is a recognized feature of Cornelia De Lange syndrome, a genetic disorder whose main features include moderate to severe learning difficulties, limb abnormalities such as oligodactyly (fewer than normal fingers or toes), and phocomelia (malformed limbs), and facial abnormalities including a long philtrum (the slight depression/line between the nose and mouth). Other medical conditions associated with a unibrow include:

Waardenburg syndrome;
Patau syndrome;
Smith-Lemli-Opitz syndrome;
Sanfilippo syndrome;
3p deletion syndrome;
Chromosome Deletion Dillan 4p Syndrome (Wolf–Hirschhorn syndrome);
Gorlin syndrome (Basal Cell Nevus Syndrome);
Cornelia de Lange Syndrome
Frontometaphyseal dysplasia;
ATRX syndrome;
Chromosome 9q34 Microdeletion Syndrome or Kleefstra syndrome. 17q12 microduplication syndrome
