Familial intracranial hypertension: a case report

Area of Science:

• Neurology
• Ophthalmology
• Genetics

Background:

• Idiopathic intracranial hypertension (IIH) is a neurological condition characterized by increased intracranial pressure without a clear cause.
• While IIH is more common in women of childbearing age, it can affect individuals of any age and sex.
• Genetic factors are increasingly recognized as playing a role in the predisposition to IIH and related conditions.

Observation:

• A familial cluster of idiopathic intracranial hypertension (IIH) was observed in a father and his daughter, developing the condition within months of each other.
• A second daughter presented with uveitis, an inflammatory eye condition.
• A third daughter experienced a distinct episode of visual loss, with the nature of this visual disturbance remaining unknown.

Findings:

• The co-occurrence of IIH in a parent and child suggests a potential hereditary component or shared environmental risk factors.
• The manifestation of diverse ophthalmological conditions (uveitis, unexplained visual loss) in other family members warrants further investigation into a possible genetic syndrome.
• This case series highlights the importance of considering family history in the diagnosis and management of IIH and related visual disturbances.

Implications:

• Further research into the genetic underpinnings of IIH may reveal specific genes or mutations associated with familial cases.
• Understanding the genetic predisposition could lead to earlier diagnosis and targeted interventions for at-risk individuals and families.
• This familial pattern underscores the need for comprehensive ophthalmological and neurological evaluations in relatives of patients diagnosed with IIH.
