    RESULTS: Fourteen boys and six girls presented with hypotonia, poor responsiveness, feeding difficulty, and infrequent, weak crying.[ncbi.nlm.nih.gov] Because of weak muscles (hypotonia), the infant is not able to drink from a bottle and may need special feeding techniques or tube feedings until his/her muscles become stronger[rarediseases.about.com] (hypotonia) learning difficulties lack of sexual development behavioural problems, such as temper tantrums or stubbornness Read more about symptoms of Prader-Willi syndrome[nhs.uk]

  • Spinal Muscular Atrophy Type 3

    They include severe weakness or 'floppiness', poor head control, weak cry and cough, and difficulty with swallowing and feeding.[rch.org.au] […] weakness and hypotonia caused by the degeneration of the lower motor neurons in the spinal cord and the brainstem nuclei.[link.springer.com] They have severe, progressive muscle weakness and flaccid or reduced muscle tone (hypotonia).[ispub.com]

  • Spinal Muscular Atrophy with Respiratory Distress Type 1

    Intrauterine growth retardation, weak cry, and foot deformities were the earliest symptoms of SMARD1.[ncbi.nlm.nih.gov] Glycogen Storage Disease Type II Classic infantile-onset disease may present with features such as generalized muscle weakness, hypotonia, , cardiomegaly as well as hypertrophic[explainmedicine.com] Ocular and facial muscles and cerebral function are preserved. There may be deformities of limbs/joints at birth from in utero hypotonia.[patient.info]

  • Adult Spinal Muscular Atrophy

    In infants, the most common demographic affected, this classically manifests as difficulties sitting and rolling, assuming a frog-leg position, having a weak cry, and having[radiopaedia.org] The examination may show all the characteristic findings of a lower motor neuron disease, namely absent/decreased reflexes, hypotonia, flaccid paralysis and muscle fasciculations[symptoma.com] They include severe weakness or 'floppiness', poor head control, weak cry and cough, and difficulty with swallowing and feeding.[rch.org.au]

  • Spinal Muscular Atrophy Type 1

    At birth, infants with SMARD1 are often noted to have a weak cry, inspiratory stridor, feeding difficulties, and congenital contractures, especially foot deformities.[genedx.com] Without treatment, symptoms of SMA1 become apparent before 6 months of age and include worsening muscle weakness and poor muscle tone ( hypotonia ) due to loss of the lower[rarediseases.info.nih.gov] Babies typically have generalized muscle weakness, a weak cry and breathing distress.[mda.org]

  • Congenital Muscular Dystrophy

    Initial symptoms may include a poor suck, weak cry, floppiness, symmetrical generalised muscle weakness and hypotonia.[neuroradiologycases.com] Congenital muscular dystrophy (CMD) comprises a heterogeneous group of disorders with muscle weakness, hypotonia and contractures present at birth.[ncbi.nlm.nih.gov] The first signs of the disorder appear in early infancy and include a weak cry, poor feeding, and weak muscle tone (hypotonia).[ghr.nlm.nih.gov]

  • Leigh's Disease

    Those three may be accompanied by a lesser appetite, vomiting, crying, and seizures.[slideshare.net] Abstract An 11-month-old boy with muscle hypotonia and neurologic deteriorations had lactic acidosis, pyruvic acidemia and alaninemia due to deficiency of the pyruvate dehydrogenase[ncbi.nlm.nih.gov] weakness.[cbsnews.com]

    In infants, the most common demographic affected, this classically manifests as difficulties sitting and rolling, assuming a frog-leg position, having a weak cry, and having[radiopaedia.org] The child presented at two months of life with intense muscle weakness affecting predominantly proximal portions of the limbs, especially the legs, muscle hypotonia, fasciculation[ncbi.nlm.nih.gov] They include severe weakness or 'floppiness', poor head control, weak cry and cough, and difficulty with swallowing and feeding.[rch.org.au]

  • Angelman Syndrome

    Babies born with PWS have poor muscle tone and a weak cry. They initially are slow feeders and appear undernourished. The feeding problems improve after infancy.[urmc.rochester.edu] Cerebellar ataxia, muscle hypotonia and tremor, though constant in childhood, tend to be attenuated in adulthood.[ncbi.nlm.nih.gov] Neonates with PWS are hypotonic, have a weak cry, and are poor feeders, but improve over time.[mayomedicallaboratories.com]
