Intellectual Disability–Epilepsy–Endocrine Disorders Syndrome (IDEES)

Intellectual disability–epilepsy–endocrine disorders syndrome (IDEES) means a person has three things together:

1. Intellectual disability (ID): learning and thinking skills are below average for age. This begins in childhood and affects daily life (school, work, independence).

2. Epilepsy: repeated seizures that are not caused by a short-term trigger only. Seizures happen because brain cells fire in a burst.

3. Endocrine disorder: a hormone problem (for example thyroid, growth, puberty, adrenal, blood sugar, calcium, or reproductive hormones).

These three features can share the same root cause (for example a gene change), or they can influence each other over time. Seizures and some antiseizure medicines can affect hormone systems (thyroid, sex hormones, bone metabolism). Likewise, serious hormone problems (very low blood sugar, very low sodium, very low calcium) can cause or worsen seizures. Because these systems interact, a joined-up plan—neurology + endocrinology + genetics + rehabilitation—is best. Neupsy Key+3PMC+3PMC+3

This syndrome means a person lives with three problems at the same time: (1) intellectual disability (limits in learning, problem-solving, and daily life skills), (2) epilepsy (repeated seizures due to abnormal bursts of brain activity), and (3) endocrine disorders (hormone problems such as thyroid, adrenal, pituitary, or glucose control). Together, these conditions can affect thinking, behavior, growth, puberty, bones, sleep, and overall health. Management needs a team approach: neurology, endocrinology, primary care, rehabilitation, mental health, nutrition, and family/caregiver training. EMRO Dashboards+2ilae.org+2

Many genetic neurodevelopmental conditions can cause seizures and also disturb hormones (for example, thyroid or growth problems). Seizures and antiseizure medicines can affect learning and mood; uncorrected hormone problems (such as hypothyroidism or cortisol deficiency) can worsen attention, fatigue, and seizure control. Early diagnosis and coordinated care improve outcomes and life skills. PMC+2Cambridge Core+2

Types

1. Genetic-syndrome IDEES
   A single gene or chromosome problem leads to ID, epilepsy, and endocrine features. Examples include tuberous sclerosis complex (TSC), Rett syndrome, Angelman syndrome, and some DEE gene disorders. The exact endocrine issue differs by syndrome (thyroid, growth, puberty, bone, or adrenal). PubMed+1

2. Brain-structure IDEES
   Malformations of cortical development, old brain injury, or perinatal hypoxia/ischemia can cause ID and epilepsy; endocrine problems may arise from hypothalamic–pituitary injury or medication effects.

3. Metabolic-endocrine IDEES
   Inborn errors of metabolism (IEM) and primary endocrine crises (hypoglycemia, hyponatremia, hypocalcemia) can cause seizures and, when chronic or untreated, lead to developmental impairment. ScienceDirect+1

4. Medication-related endocrine overlay
   Some antiseizure medicines (e.g., enzyme-inducing drugs) and chronic uncontrolled epilepsy can disturb thyroid, sex hormones, and bone health, adding an endocrine layer to pre-existing ID and epilepsy. PMC+1

5. Hypothalamic–pituitary axis IDEES
   Lesions or genetic disorders that directly affect the hypothalamus or pituitary produce endocrine problems; seizures and ID may co-occur due to the same central pathology.

• The developing brain and the hormone systems grow under shared genetic control; a single gene error can affect neurons and endocrine glands together.

• Seizures can stress the brain and alter neurotransmitters (GABA, glutamate) that also talk to hormone control centers.

• Antiseizure medicines change how the liver handles hormones and vitamin D, which can lower thyroid levels or weaken bones.

• Endocrine crises (very low sugar, sodium, calcium) can trigger seizures and, if repeated or prolonged, harm development. PMC+2PMC+2

Common causes

Note: In one person there is usually one main cause. Doctors look for it with history, exam, and targeted tests.

1. Tuberous sclerosis complex (TSC) – a genetic disorder causing cortical tubers, early-life seizures, ID; endocrine issues may include puberty or thyroid variations and bone health concerns. PubMed

2. Rett syndrome (MECP2 variants, mostly girls) – developmental regression, epilepsy, autonomic/endocrine dysregulation (growth, puberty, bone). PubMed

3. Angelman syndrome (UBE3A) – severe ID, ataxia, frequent epilepsy; feeding and sleep–endocrine issues are common. Verywell Health

4. Fragile X syndrome – variable ID, epilepsy in a subset, endocrine/behavioral features; may show puberty or thyroid variability. PubMed

5. Chromosomal copy-number variants (e.g., 15q11-q13, 1p36) – can combine ID + epilepsy; endocrine features depend on genes affected. Cambridge Core

6. Developmental and epileptic encephalopathies (DEE, many genes) – early-onset refractory seizures + developmental impairment; endocrine abnormalities may coexist or reflect treatment effects. PMC

7. Perinatal hypoxic-ischemic brain injury – causes lasting ID and epilepsy; pituitary injury can cause growth or thyroid problems.

8. Malformations of cortical development – abnormal brain layering leads to epilepsy and ID; endocrine issues may come from hypothalamic involvement or meds.

9. Congenital infections (e.g., CMV, toxoplasmosis, Zika) – can produce ID and epilepsy; endocrine problems may occur when the hypothalamus/pituitary is affected.

10. Inborn errors of metabolism (e.g., mitochondrial disease, urea cycle defects) – metabolic instability causes seizures and delays; some directly affect endocrine pathways. ScienceDirect

11. Thyroid hormone disorders in early life (congenital hypothyroidism) – untreated, can cause ID; can also predispose to seizures in severe cases.

12. Chronic hypoglycemia (e.g., congenital hyperinsulinism, adrenal insufficiency) – recurrent low sugar provokes seizures and harms the developing brain if uncorrected. Neupsy Key

13. Electrolyte disturbances (hyponatremia, hypocalcemia, hypomagnesemia) – trigger seizures; if recurrent/untreated, development suffers. Neupsy Key

14. Autoimmune encephalitis – seizures and cognitive problems; some cases involve endocrine autoimmunity.

15. Brain tumors or hypothalamic–pituitary lesions – seizures and ID depend on location; endocrine changes are common.

16. Traumatic brain injury (early childhood) – can lead to post-traumatic epilepsy, cognitive deficits, and pituitary hormone issues.

17. Neurocutaneous syndromes beyond TSC (e.g., Sturge–Weber) – epilepsy with developmental impact; endocrine issues vary.

18. Medication-induced endocrine changes from antiseizure medicines – thyroid dysfunction, menstrual irregularities, low bone density add an endocrine layer to existing ID + epilepsy. PMC+1

19. Genetic channelopathies (e.g., SCN1A in Dravet syndrome) – severe epilepsy and developmental slowing; endocrine effects may be secondary. PMC

20. Syndromic chromosomal disorders (e.g., Down syndrome) – higher epilepsy risk than general population; endocrine issues like thyroid disease are common. Cambridge University Press & Assessment

Symptoms and signs

1. Delayed milestones – later than expected sitting, walking, or talking.

2. Learning problems – trouble with school skills, problem-solving, and memory.

3. Seizures – repeated events with staring, stiffening, jerking, or collapse.

4. Behavior and attention difficulties – hyperactivity, anxiety, or autistic features.

5. Speech and language delay – few words, unclear speech, or difficulty understanding.

6. Motor problems – clumsy movements, tremor, or stiffness.

7. Feeding problems – poor weight gain or chewing/swallowing issues.

8. Sleep disturbance – frequent waking, sleep–wake reversal (common in some syndromes).

9. Short stature or growth changes – due to pituitary or thyroid issues.

10. Early or late puberty – hormone timing is off.

11. Irregular periods or fertility issues – in adolescents/adults with ovaries or testes.

12. Thyroid symptoms – tiredness, cold intolerance (low thyroid) or palpitations, heat intolerance (high thyroid).

13. Bone health problems – fractures or low bone density, especially with certain antiseizure medicines.

14. Blood sugar symptoms – shakiness, sweating, confusion (low sugar) or thirst and frequent urination (high sugar).

15. Adrenal symptoms – fatigue, low blood pressure, salt craving, or crises during illness.

How common is epilepsy in people with ID? Estimates vary by setting, but many studies show much higher rates than in the general population, and seizures are often drug-resistant. seizure-journal.com+1

Diagnostic tests

A) Physical examination (observe and measure)

1. General growth check – height, weight, head size; looks for small or large head and growth problems that point to brain or hormone issues.

2. Dysmorphology exam – careful look at facial/body features that might match a known genetic syndrome.

3. Skin exam – café-au-lait spots, hypopigmented macules (ash-leaf in TSC), hemangiomas; skin clues often point to specific syndromes. PubMed

4. Neurological exam – tone, reflexes, coordination, gait; helps localize brain involvement and guides imaging.

5. Puberty staging (Tanner staging) – checks timing of puberty to detect early/late patterns.

B) Bedside/manual tests (simple tools in clinic)

6. Developmental and cognitive screening – age-appropriate tools to map strengths and needs in learning and daily living.

7. Seizure diary review and video capture – timing, triggers, and semiology help classify seizure type and choose tests.

8. Vision and hearing screening – untreated sensory loss worsens learning and behavior, so it must be checked early.

9. Bone fragility risk screen – asks about fractures/falls; prompts bone labs or scans if risks or enzyme-inducing drugs are present. PMC

10. Medication reconciliation – reviews all drugs and supplements for interactions that affect seizures or hormones.

C) Laboratory & pathological tests (blood/urine and specialized)

11. Thyroid panel (TSH, free T4 ± T3) – common, simple first test when growth, energy, temperature tolerance, or cognition fluctuate.

12. Metabolic screening (glucose, electrolytes, calcium, magnesium, liver/renal function) – looks for trigger causes of seizures and correctable contributors to developmental slowing. Neupsy Key

13. Endocrine panels tailored to symptoms – morning cortisol/ACTH (adrenal), IGF-1 and GH studies (growth), prolactin, LH/FSH and sex steroids (puberty/fertility).

14. Vitamin D and bone turnover markers – low vitamin D is common in people with epilepsy on enzyme-inducing drugs and contributes to bone loss. PMC

15. First-tier inborn error of metabolism tests – plasma amino acids, acylcarnitine profile, urine organic acids, ± plasma total homocysteine; these can uncover treatable metabolic conditions. ScienceDirect

D) Electrodiagnostic tests (brain electricity)

16. EEG (electroencephalogram) – records brain waves to confirm epilepsy, classify seizure type, and sometimes point to a specific DEE pattern. PMC

17. Prolonged/video EEG monitoring – helps capture rare events, separate epileptic from nonepileptic spells, and guide medication.

E) Imaging tests (pictures of brain and bones)

18. Brain MRI (preferred) – shows malformations, old injury, tumors, and hypothalamic–pituitary problems; essential when ID and epilepsy coexist.

19. Pituitary–hypothalamic MRI (focused) – if growth, puberty, or adrenal problems suggest central endocrine disease.

20. DXA bone density scan – checks bone strength when fracture risk is high or when long-term antiseizure therapy could harm bone mineral density. PMC

Frequently asked questions (FAQs)

1. Can fixing thyroid problems help seizures and learning?
   Yes. Treating hypothyroidism and other hormone issues can improve energy, attention, and sometimes seizure control. Keep levothyroxine timing consistent and monitor labs. PMC

2. Which seizure medicine is “best”?
   There is no single best drug. Choice depends on seizure type, age, sex/pregnancy plans, comorbidities, and interactions. Levetiracetam, lamotrigine, valproate, topiramate, and others are chosen for specific seizure patterns and side-effect profiles. PMC

3. Is valproate safe in women who may get pregnant?
   Valproate is effective but has major pregnancy risks; specialists usually avoid it in people who can become pregnant unless no alternatives work and strict contraception is used. FDA Access Data

4. Do rescue nasal or rectal benzodiazepines replace daily meds?
   No. They are for seizure clusters only, with strict limits on frequency. Continue daily antiseizure medicines. FDA Access Data+1

5. What if a seizure lasts longer than 5 minutes?
